is all of this because of my stutter?

is all of this because of my stutter? I'm 17 years old, male, i have good friends, i go to parties with some of them, i have good marks in school, i'm pretty handsome, not like dayum but i like the way i look. The thing is 2 years ago my stutter went from mild/not a problem to not that bad but being a problem. This usually depress me, i feel stuttering is the only thing that doesn't let me be happy, that doesn't let me be who i am. Other things like not being able to make eye contact (it feels so awkward), after saying something to someone, feeling like it sounded really dumb, etc. This things seem to be caused by low self-steem, so another thing to the list. is all of this caused or related to stuttering? i love you all
