Really bad anxiety attack.

I don't how to say this but I'm just fed up of these anxiety attacks, I just feel like hiding somewhere, away from everyone, every problem and sometimes I feel I wish I don't exist at all, my whole is on fire, because of anxiety my body temperature rises up. I can't even breathe properly, I feel like I'll colapsed at any moment. This shit make me do self harm. I feel like killing myself, I don't know what to do anymore, I already have bi polar. Oohh man I wish I could just not feel this way. I'm so scared. Please God I can't take this shit anymore, I just want to be normal. 😭😭😭
