I need ideas on how to stop my stutter asap

I need ideas on how to stop my stutter asap 19M , I have been stuttering ever since I was around 10 but as I am growing up I realized that I can't handle it anymore , neither do I want to accept myself with this flaw. My older brother did have a stutter at around 2 years old but he got rid of it the same year. I have taken phenibut + proparonol , and although it worked great the first day , it barely works now (maybe because It's low dose 250 mg phenibut at day and 250 at night). I am almost certain this is based on my anxiety since there were times I was doing presentations without stuttering once , days when I was talking to people without stuttering. But now it's gotten worse at university and there is way more pressure , I'll do anything at this point , I'll take any pills , I'll go to a speech therapist if it actually helps although many people say that it won't make much of a difference.
