So, I am a 23F, working in my first job for about a year now, and I am not sure if I am doing a good job or not. I recently got diagnosed with autism, and things feel so different now. A lot of things make sense, but there are a lot I am still trying to unlearn and relearn. But one thing I know is that I need a job, but I am not really doing great at that.
Some problems I am facing are:

• They changed my work portfolio, and I am no longer working for the work I came for but have been shifted to proposal writing and connecting with people (both things I am not good at).
• There are times I check my emails and submissions like 10 times, so I don't make a mistake, but I still sometimes send wrong things, forget to rename things, etc. and yeah, when my manager scolds me for that, I too feel like shit
• I get shamed a lot as I take too much time as compared to my colleagues when it comes to work; I've been told I am not doing my best and need to "up my game."
• Two of my teammates left the team, and they still haven't hired anyone new. I've been working 3 people's jobs, and many times my mind goes blank because there are, like, 10 things with the same deadline or "urgent."
• Oh, and I am on minimum wage. Every time I have asked for a raise, they have asked what I have even done or accomplished, and I go silent most of the time.
• My self-confidence is down the drain; I am not sure if I am even good at anything. My software skills are going away because I am not practising anymore.

It's my first post, so idk how exactly it happens, but I just wanted to rant and possibly get some kind of explanation or answer.

Also, my English is not great, so spare me, please.
