Exhausted by Life Long speech impediment

Exhausted by Life Long speech impediment Stuttering has always hindered my life for as long as I can remember. Countless times I avoided conversations so I wouldn’t embarrass myself, sometimes to my detriment. Because of this my social skills and overall self esteem has taken a tole. I’m currently a EMT, I love my job because I get to help others but my inability to converse and communicate with others makes this feel like I’m fighting a losing battle. I have good days where I go the entire day without a hiccup in my speech but for the majority of the time I’m constantly struggling getting my point across . Sometimes when I find my self getting stuck while talking , I get these condescending looks like I’m stupid and unable to do my job, after a while you start second guessing yourself and it takes a hit at your psyche. The kind of field I’m in, you can’t be second guessing yourself, you have to have full confidence in yourself and I lack that sometimes because of mine speech impediment. I wanna further my education but I’m not sure if it’s a complete waste of time, I know the book work wouldn’t be much of a problem, I’ve always been a great student. My main worry is when I’ll have to start talking and communicating with doctors and higher ups in high stressful situations. I just want somebody to talk too about my situation and if there’s any advice you guys have, feel free to comment.
