Need advice

Okay so lately I’ve been depressed literally every single day, I’ve gone back to bad habits(cutting and suicide thoughts) I’ve been irritable and sensitive asf. I’ve had to delete my Instagram and my Facebook because I just can’t stand to see people happy and me be so miserable. I know I’m going through a lot including a bad breakup but I’m not okay and I don’t know what to do. I want to be happy and confident and okay on my own but I don’t know how. Helpppp please!
