I'm tired

I'm tired Every time I want to talk I can't, it happens with anyone in any situation. Most of the time I stay quiet and I seem like someone boring, I just feel afraid for my future,I feel increasingly incapable of working, studying, or finding a partner. I tried to study but I couldn't speak in class, at every job I am very quiet and with a girl I am also too quiet why can't I speak? My stuttering is getting worse, it's been 7 years like this, avoiding all my responsibilities just out of fear.
