If you are genuinely depressed then speaking a docter or a therapist is likely your best option. The ideas that you have put forward do not improve your quality life and many actively harm it. If your stutter is the thing that is genuinely getting you down then have you tried speech therapy? This could improve both your confidence and level of fluency. If you do not want to go out and get therapy then I would recommend the book Self Therapy for the Stutterer. (https://www.stutteringhelp.org/Portals/English/book0012\_11th\_ed.pdf) Moving beyond that, I could consider what exactly is getting you down. Are you having trouble socialsing? Are you have difficulty at work or school? Identifying what parts of life are making you miserable will allow you to work on improving them. Perhaps it will lead you take a hobby or reach out to old friends you have lost touch with etc.
