Anxiety advice

I've always had trouble with anxiety, but I could always control it. The last few weeks have been horrible. I can't eat without feeling sick and I'm having bowel problems. I can't sleep at night because I can't shut my brain off. I've been crying for no reason (and no I'm not about to start my period so it's not pms). My heart is always racing and I don't want to do things I used to love to do. I don't want to be around people anymore not even friends. I'm going to the doctor tomorrow but I don't know if that'll help. I've tried therapy but I didn't work. I'm just tired of having this weight on my chest. I don't know what to do. Can anyone give me some advice to help ease my anxiety please😞
