PTSD (post traumatic stress disorder) is an anxiety disorder, if that helps...

(((((((newyork))))))

Its hard when you feel like that, isn't it? Its like there's NO escape....That anxiety is SO intense and all consuming...
((((((hugs))))))))

Plus being 20 is the sort of age, in my experience (I'm 35) when that sort of feeling can be very active anyway..

Are you seeing a therapist? That might help.
Also possibly anti-anxiety medication?

I hope you find the support you need.
