weird withdrawal timings
hi guys, just wanted to see if this is normal and how long it should take to improve:
I smoked weed every evening + most afternoons for about a year, partially so that I could cope with some side effects of a prescription medication for adhd. About 2 weeks ago, I finally decided enough was enough because it was really fucking me up and I realised that my life had been much worse since starting smoking. I quit, and felt amazing. I had a couple rough nights of not much sleep, boring hangouts with friends who were smoking but I wasn't, but I had way more energy, passion, focus and a better outlook on life. I noticed that about a week after quitting, I started to get some pretty rough diarrhoea, which is slowly improving. I thought that I had gotten away with minimal withdrawals. Now, about 2 weeks later, I am starting to get anxiety. I get that weird feeling that I am a bit of a pain, for example, I just got home after getting a lift from my mate, but the whole time I felt like he was annoyed at me for driving, even though I know he wasn't because he offered the lift to me. Every time I have a social interaction with someone that I don't know too well, I get a really really intense, cringe/anxiety feeling. I saw my mates older brother earlier, we just said hi and how are you, then when I was walking away, I felt like I needed to run away. I felt like I was really weird and awkward, even though I was super nice and he was too. I keep getting this. Every small, insignificant social interaction results in me replaying the situation in my head, making sure that every single word was normal. And it generally is a completely normal and forgettable interaction. I just have this feeling that something is not right, but when I think of what is wrong, I cannot actually come up with anything.
I just want to know if this is normal? I see loads of people saying they get anxiety but I don't know why I am getting so anxious 2 weeks after quitting, with the first and usually most difficult part being almost nice. Has anyone got any good tips on how to help this? How long does it typically take to lose this feeling? I am doing my A levels right now, so I am more stressed than usual but this is not normal. I don't think that this has anything to do with my adhd meds, because I don't notice this improving or getting worse when they are in effect/worn off.
Thanks for reading I hope that wasn't a load of waffle!!
