Could I actually be BI-Polar?

I am goin on 22 years old and have always felt like I been on an up and down mood swing ride... I used to just think it was growing up but now I think I could be that much more deeper because instead of gettin better it's getting worse... And I am even starting to hear and see things that aren't there but mostly hearing things The visions were more so when I was younger (One of the reasons I sleep with my door closed till this day.) I can stay awake for days at a time or sometimes the complete opposite sleep the whole day and still feel sleepy... Sometimes I feel depressed and other times like I have ADHD or somethin... I get very hyper and talkative and I can't control it for anything... I get anxious a lot and I can go from eating fine to eating like once a day and not on purpose... I was prescribed Prozac a few months back but I didn't feel like it worked all that much and Trazadone was prescribedc to help me sleep but I told the doctor that I don't think it was working and one of those or both together made me feel more irratable quicker... I am makin an appointment through magellean today but I still really would like to get a clearer thought on if it was worth it or not... I've always felt depressed sometimes almost suicidle but not really cuz it's more a feeling that I don't care if I live and when I do things I don't think death but what if... like when I'm driving sometimes I'll start thinking how fast I can go before I crash and then when I snap back I am speeding... I don't feel depressed 24/7 but months at a time and then it's like it just leaves and one day I wake up talkative and ready to do whatever... It has even gone as far as poppin ecstacy and drinking to smoking weed when I feel happy just cuz I feel like I can't be touched... I just want to feel normal again... No drugs... Just a happier me living life... It's so frustrating and since my guy and mother are pushing me to get help I am because I don't want to keep scaring them anymore
