My stutter makes me feel like a freak.

My stutter makes me feel like a freak. Just now I saw some friends in a discord call so I jumped in, they said I should get the game Unturned. I said I wasn't at my house and it wasn't my PC so I didn't know if I could just download it. My stutter was pretty bad so half way through one of them started mocking me going "um uh um uh m m my" so I just left the call. I just said eith my head down on the desk for ten minutes trying not to cry. I hate my stutter, at times it makes me feel like I'm not even human. I just want to talk.
