Will my memory go back to normal? I've been addicted to cannabis for a while and my memories gone to s**t and i feel like a mess. pls help?

i'm 20 and have aspergers syndrome. I've always had a very good long term memory but after i started smoking weed on a daily basis all I've got now is a very bad memory and i can't always remember words and phases when i know that i know them and when in conversation it makes me look stupid, when i was younger it was the exact opposite and people used to say i was 'bright' and 'intelligent' but now i just feel like an idiot. i was smoking £40 worth of weed a day but i've cut back now and now i'm just doing a £10s at the weekend. i see myself as been ugly and i can't stand looking at myself in the mirror, i fear i'll never be loved and i won't have any mates when i'm older. i have no job and talking to my parents is like talking to a brick wall and i don't feel their important in my life, they've always been more interested in my cousins who grew up in care. i'm unemployed and have been for a while and i'm not getting any responses from employers and i feel isolated, what should i do?
