I've started hating my life due to my stutter.

I've started hating my life due to my stutter. I've lost the will to practice and even to live this life. I occasionally think about ending my life. I keep thinking about my stutter even when I am at work and due to that my work has taken a hit. And my colleagues do not like talking to me because I get stuck on every 2nd or 3rd word. I believe they think I'm dumb. I am not able to speak in meetings or socialise anywhere. I don't fear stutter but I feel digusted when I stammer because I lose the intent to speak. I'm 27 and life feels so heavy. I see other people who are fluent, they just have it all easy. Although, I'm a public speaker and read a lot specifically about spirituality but these encounters at work or in the world outside have made me numb. Even on the days I do not stutter I don't feel happy now.
