As title says. I am severely at the edge dealing with crippling anxiety, the nasty kind that literally paralyses you. It's incredibly though going through the recent days and the feeling of mentally breaking is just overbearing. 

I should start with an SSRI (Lexapro) asap but for the life of me i cannot do it. Reading here and on the web that the first days might give one *increased* anxiety is just absolutely not imaginable.

I got tavor alongside but i can't take that either, i am terrified of getting a heart attack or become addicted after a week. 

How did anyone here with severe GAD overcame their fear of starting with Lexapro or any other SSRI ? 

All rational thinking like taking it in a save environment, with someone else around etc does not reach my mind. 100% blocked
