Some coworkers don’t like me

Some coworkers don’t like me I’m quiet at work because of my stutter and only really relate with a few people. Some people seem to not like me and I’m assuming it’s because I don’t say anything to them. For example I don’t say goodnight to anyone when leaving because I always stutter terribly on the g in goodnight which is extremely embarrassing. I’m also not really a fast thinker when it comes to responding to funny small talk and I believe it’s because I’ve always been quiet due to my stutter and never got that experience of really relating well with others. I try to ignore the people that don’t like me and not let it get to me but it can be hard at times.
