My 3 shitty problems and their shittier solutions............please help me come up with better ones

My 3 shitty problems and their shittier solutions............please help me come up with better ones Hey r/stutter Im a 19 year old Chemical Engineering student in Canada. Ever since I was a child I have stuttered pretty bad to the point where it would seem as if I had tourretes each time I would speak. This caused me to be pretty much isolated socially while growing up and not learning basic social skills and I know realize it has completely fucked my life. 1) After trying my ass off to make friends and connections for all these year and being constantly rejected I am lost on what I should do or how I should approach this as the loneliness just drives me deeper into this depression. 2) I am 6ft, fit and slightly above average looking. Yet once I talk I can sense my worth falling faster then the stocks in the great depression (being an immigrant doesnt help) .Truthfully I would consider myself alot less desirable then 95%+ other males my age and I am seriously considering quitting getting a girl and instead setting a monthly budget aside for hookers etc. 3) I got rejected from a McDonalds job 4 times after my interview and I fear this kind of rejection may slip into my professional career and I am know doubting the worth of even pursuing one knowing ill never live upto its full worth and am wondering if should go about a minimalist and free lifestyle Not to sound rude but please give me realistic advice and not just 'put yourself out there and people will like you for who you are' etc and please realize the true depth of this problem and how to fix it. Thanks.
