I am attending my friend’s wedding early next month and for some reason, I absolutely dread it. I don’t really know anybody, and she invited me as basically one of her only friends. I’m pretty sure her bridesmaids will only consist of her family and her best friend.
One of the reasons I’m really dreading it is because she comes from a very sheltered community and I just feel like the whole thing is gonna be really awkward. She and fiancé were encouraged to marry young because it’s basically expected of her…kinda the same stuff you’d hear from that type of people. That already makes me uncomfortable.
The other thing too is that I feel like recently, she hasn’t treated our friendship very well. She’s kind of acted like I’m more of a supporting character than her actual friend. She’s even outwardly prioritized her friend over me when we are together (ie: more sympathy/ empathy for her as opposed to something else I’ve said during a conversation, regardless of the context).
I also have ADHD and she treats me like I’m a quirky silly gal than an actual serious woman with an actual life and goals (almost like an exaggerated Type A vs. Type B but I’m not really a Type B person she just sees me that way).
I’m trying SO HARD to be supportive and happy for her, but I just can’t get excited. I bought her registry gift and am RSVP’d because I do care about her but man I’m just so conflicted and I don’t know why.
Also for clarification I am in a happy relationship so it’s not out of jealousy for her finance or something lol.
Why do I feel this why? How can I feel happy and get over this resentment?

I had one of my worst shifts today that I’ve ever had.
I am a hostess at a pretty nice steakhouse. Tonight was one of my first super busy shifts that I’ve had since I came back from college to work.
Usually, it’s not a big deal and I’m not bad at my job, but I ended up accidentally skipping a server for almost 3 hours because the tables kept shifting around, and I just never noticed that he hadn’t been seated. Essentially what happened is two big parties came in, the rotation got messed up, and we accidentally double seated another server with the party. This was my and the other two server’s mistake.
He had another section so it’s not like he never got tables, but he got really mad at me. I apologized, but proceeded to hold a grudge and guilt trip me and the other hosts. He wouldn’t even look at us.
I’m a people pleaser so I just internalized it and I feel like absolute crap. I cried in my car as soon as I clocked out. I am dreading going back in tomorrow night for my other shift because I don’t want to see him and I’m terrified I’ll mess up again.
Advice?? Support?

For context, I am a 21F and friend and I have known each other for the better part of two years. We met in my second year of college.
Back when we first met, she had a crush on this kid, but I didn’t know him very well and I did not know that he was a minor at the time. They both come from EXTREMELY conservative and sheltered backgrounds, which I feel like plays a huge part in their relationship (they literally have had adults watch over them/ accompany them on their dates during their “courting” period because he WAS A MINOR).
However, as soon as he turned 18, he proposed her and now they are getting married.
Do what you want I guess. He is technically an adult, but I wish I had a good way to get out of this wedding without offending my friend.
Honestly, she’s recently been treating me like a bit of a jerk. Especially within the last year or so she has acted like she’s better than me or that I am a “quirky, spontaneous lol” friend. She’s even said I’m a “college friend”, to her. Whatever that’s supposed to mean.
She’s kind of one of those people that assumes I am funny and silly all the time and don’t take life seriously. This combined with how uncomfortable it feels going to a wedding where all these people are rooting for this boy to marry a literal grown woman just feels so wrong. I’m just worried if I don’t go, it will breed bad blood between us and we share a lot of mutual friends. She is still my friend too and I care about her...I just don’t support this decision…

I RSVP’d just in case, but idk. Would I be the AH for canceling or finding an excuse? Is it bad that I feel this way even though they’re happy? Should I find a reason to go not go??

EDIT: A lot of folks are saying the age gap isn’t insane (which is true), but it’s not really the ages that bother me. I am of the mindset that you should only get married once you’re ready. You should, in my opinion, be able to support yourself and not have to be solely dependent on another person. My friend is marrying this guy with no job and his job is very unstable. It also bothers me that she doesn’t really have a support system and they have gone on very few dates unsupervised (one of their parents would accompany them). They also want kids soon.
I’m not saying you have to live with someone before you marry them, or even have been together a long time. What gets me is that they don’t KNOW each other and they’re both so young. It scares me a little. Sorry if I was projecting.

I appreciate all the comments though. I do think because I RSVP’d, I am, unfortunately, the AH. I will likely go because I’m not willing to end my friendship over this, but I agree with many of you that this friendship, after this, will likely not last.

I'm a freelance graphic designer, but I'm still really new to working for people professionally. I recently had a gig go really bad, as I had completed my end and got paid, only to have the client call me this morning demanding a refund because the files were not right. She literally had another graphic designer with her claiming I had no idea what I was doing and that I was nowhere close to what they needed. I gave them a full refund, but I feel like crap. I'm worried they'll review me poorly. I've been scammed, ghosted, and now this. I feel like I have one out of every 50 clients actually be good.
