Maybe life isn't worth living after all

Maybe life isn't worth living after all Male 21 Years old. Have been stuttering since I was 8. Also have severe ADHD-PI. By now I thought I wouldve outgrown this but no, it has gotten much much worse compared to when I was younger. Have been to multiple speech therapists because my parents pretty much forced me for my own good which I appreciate it now looking back at it. The sessions were of little to no use. In fact, I think it made it worse since it made it much more ingrained in my mind that I have a serious issue at hand. On a severity scale I would put it at around 8-9 out of 10. Very HARD blocks. I can't even repeat sounds anymore it's just silence. My Stuttering comes from Genetics. My Dad, 4 Uncles, Grandpa, Grandma, and 3 Cousins Stutter. This is going to be the worse part, I went to a trade school for plumbing when I was 18 fresh out of high school and got my certificates which is nice and all but after that I haven't done ANYTHING to find a job and have just been staying with my parents. I am terrified, this might sound like an exaggeration but it is real. I am living this life that I can't escape, sometimes I look at myself in the mirror and I don't even know who I am anymore. I still and will probably never accept that I am a Stutterer/ will be a Stutterer for the rest of my life. I can't fathom living the next 50-60 Years like this, no way. I have nearly given up completely, my mental health is deteriorating rapidly and Suicide seems more and more appealing. My parents always have to order my food for me because I can't do the simple thing that 99% of people on this planet can do, speak fluently. Wasted Potential.
