My stutter certainly has played a big role in my depression, especially when I was younger. I have clinical depression for other reasons, but personally I know my stutter did make it worse at times in my life. I think the biggest thing is just acceptance. Accept what you can't change. I know that's hard, but it did help me to accept the things about me or in my life that I don't have control over. I still become very down on my self at times when my stutter is bad. I'm 25 now and still struggle with those feelings, but nothing like when I was younger and it really kept me from leaving my house. I do understand that our situations may be different, but there is certainly hope for more confidence. Your situation doesn't have to improve for you to improve your outlook on your situation - but I know it's easier said than done.
