Life seems hopeless

Life seems hopeless Today a guy randomly asked me my name in the gym and it literally took me 10-15 seconds to say the first letter. I feel like life isnt worth living like this. Rather be dead than alive. I have plans of going abroad for my masters degree but if it's like this it's gonna be too hard for me to adapt to a new environment. Just feel it's not worth going through all of this pain everyday. I am currently 22 and i seriously don't know how I'm gonna cope with stuttering for the rest of my life. Have been through therapy but it was in vain. Seriously want to start life afresh .
