Horrible Anxiety

Lately my anxiety has been ruining everything. I feel like I'm suffocating in a way. I get good news and I can't even really enjoy it or cherish that moment because my anxiety hits me with all the "what if's" and "you're going to screw everything up and embarrass yourself." I don't even feel like myself anymore. I've tried talking to people and I'm on medication but nothing is really helping. Coping techniques aren't working either. Do you ladies have any advice? I'm really struggling and could use some help.
