Frankly, I feel like you. 24M, yesterday I walked home with someone from my class, stuttered the whole way. When we parted ways, I felt terrible and ashamed. It's really hard for a shy guy to have on top of that a stutter. It really worsens the issue. I feel a bit depressed, worthless and broken. Like you. This event is just the tip of the Iceberg. I can't make social connection like normal people because my subconscious is rigged to fear talking, opening up to people. I barely talk to people and I don't even realize it because of how long I've been doing this. It's the normality to me. People often dislike me because I appear condescending and mean because of my resting bitch face and me staying silent. And it's hard to convince them that I'm super nice and friendly behind this mask. I'm sorry to not being able to give you advices but at least you know you're not alone in this situation.
