help? how to fix my life?

[ijustcametosayhello]

when i first started high school (im a freshman) i was an okay student. but all this pressure made me go into a deep depression. i mean i already had depression and bipolar disorder. it just got worse. i ruined my relationships with everyone. friends, family, potential boyfriends. i explored options of making me feel happier. like energy drinks, junk food, etc. i used to be one of those people who criticized potheads. i now smoke weed every day. i hang out with a bunch of potheads and most people i talk to are potheads. i took adderal today. my heartbeat was incredibly fast although i didnt experience severe symptoms. my friend passed out though. but probably because she smoke weed, took the pill, took ibuprofen, and half an acid tablet. but i feel like my life is really going down the drain. my grades a dropping like mad, my attendance is extremely poor (13 unexcused absences) i feel like if i continue on like this i will become nothing. please. help. i know this wasnt really a question but i felt like like i needed to get this out.
