Stammering affects the way other perceive me.

Stammering affects the way other perceive me. Hello, I am 22 year old male with a stammer. I have been doing a lot of thinking today about how much my stammer has affected the way I come across to to others. My technique to avoid stammering is often to only speak when I am confident that I won't stammer. This has resulted in me being afraid to initiate conversations with others , telling jokes, ordering food etc. At work I am the quiet guy, often observing and chiming into others conversations however, I don't really add much often just agreeing and giving one word answers. I know deep down most of my colleagues probably think I am boring, cold and just don't have any intrest in their lives. I feel as if years of trying to hide my stammer has ruined my social development. I feel too scared to ask questions such as "How are you" "How was your weekend?" etc. I am very sensitive towards my stammer. I hate this, as a kid i was very energetic, talkative and made everyone laugh. I was a very funny kid. I just don't know what happend lol. The more conscious I became of my stammer, the more my personality died. I hardly have friends any and just feel like a nobody. I am really scared for my future at the moment. Most people don't realise how vital communication is and being able to express yourself through words. I am sick of being the quiet guy because I know deep down I am not. Its just that I am shit scared that I will stammer. Can anyone relate with this?
