Well basically I was super excited to meet my new flatmates today, and when I got there, the flat was empty. So all 5 of them are moving in tomorrow instead of today

I cried in my room for a while and then went outside and met some people and went with them with their flat to drink, then we went to the park and smoked weed, and then went back to the flat and played Mario Kart, and then I went back to my flat after a couple hours cos they said they were both tired, and now I'm alone again.
I had been one year with no drugs on the 9th Sep 2020 so this was the first day I've smoked in a year and idk how to feel about that. When I was smoking weed with my ex I was having a bad time and being panicky, and he told me I shouldn't do drugs cos I react badly on them. But I think that I only reacted badly with HIM, because he would be mean to me. So today I thought I'll have a good time because I'll be in good company. And yeah, it was good! I was just feeling a bit like I was losing control of myself towards the end, and thinking that they both secretly hate me or I'll embarrass myself, or offend someone by accident or act stupid or just being self-conscious in general. But overall it was good.
Idk when I got back into my empty flat I just felt so sad & losing touch with reality, I started texting everyone I know, and most didn't reply. Idk how I'm gonna survive being on my own cos the fact that I cried one hour after I moved in cos I was lonely isn't a good sign. I just hope my flatmates are here tomorrow. UGH.
Idk what you can say to this, but if anyone can give me any words of encouragement then please do cos I need it. And I'll try and get onto group chat in the evenings even though that is the time when I need to be social the most so I don't even know if I'm gonna be able to go on group chat regularly like I used to and it helped me a lot. I wanted to defer my entry because I didn't feel ready to go, esp not with corona and stuff but my dad screamed at me and said "there's no logical reason why you should defer!" and that fucked with my head and now I'm here.
