LIFE SUCKS

Summary

I'm an 18yo with bi-polar depression. My family life isn't that great, My mother was too busy with her abusive boyfriend while i was growing up, my sister and i can't be in the same room for 5 minutes, my dad was largely absent for my childhood and trying(failing) to make up for it now. My best friend refuses to spend any time with me or take my calls due to his girlfriend (who hates me). The reason we became friends is our mutual affection for the ganja (shrink says it's unrelated to my depression). I was a loner at school who always kept quiet and withdrawn at the back of the classroom. I struggle to hold conversations with strangers which makes employment and romance cripplingly difficult. I also become paranoid about perceived reaction from people when it comes to dating. I wanna know what you guy's think, Am i normal?
