Somebody give me some coping mechanisms 😭

My anxiety has been SO bad lately. Bad to the point where I’m losing weight, throwing up, crying for no reason. I don’t want to leave the house or go to any public places and I’m just so tired and exhausted. I just got prescribed Prozac so hopefully that helps but in the meantime I just don’t know what to do with myself. I don’t know how it’s gotten this bad, it’s probably never been this bad in my life. I feel like I lost myself. I feel like I’m going to lose all my friends and boyfriend because of it, even though in the back of my head I know that won’t happen, but it’s this stupid anxiety talking. I’m hopeless and don’t know what to do with myself anymore..anyone have any tips?
