Reading your story really hit me hard emotionally. I’m 22 and my stutter is also holding me back a lot. I only have a high school diploma and I’ve dropped out of both college & uni. Though I do plan on going back to Uni this year because I really want a degree. I haven’t even taken a job yet because I’m terrified of stuttering in front of customers. I only have one friend and a few acquaintances here and there. I need more friends but it’s really hard. Anyways, I think that you should definitely do speech therapy, even if it’s the 4th time doing it, like me lol. Also seeing a good psychologist frequently should help gradually with your anxiety, low self-esteem & confidence. I hope things get better for you!! :)
