Stutter really beginning to get me down

Stutter really beginning to get me down Hi everyone, I've been a stammerer ever since I was a little kid, apparently it was quite bad as a child but seemed to improve through my teenage years, almost to the point of fluency. Im 24 now and its coming back, a lot. Especially when someone asks me to repeat what I just said or I have to give clear one-answer information, like my name or address. Anyways, I had a phone interview today (I'm unemployed by the way) for a job I really wanted and it went so badly. Found it so hard to calm myself down and I kept on stammering, I was asked to repeat myself a few times and that made things so much worse. Im considering seeking medical help, but I have heard mixed things about the effectiveness of speech therapy, what have your experiences been? Its really beginning to get me down now, just want to be able to talk like I can when I'm on my own... :(
