Helping my brother

Helping my brother My brother has been stuttering for a long time but in the last six months it has gotten a lot worse and I'm scared that it will affect him going into highschool. Parents don't wanna take him to a speech therapists and I'm in college so I'm basically broke for the time being and can't afford to pay for that myself. Is there anyway I can help him? I can devote all my time to learn and help him but I don't know what to do. I do recognize though that it comes from a place of anxiety and social anxiety since he doesn't stutter talking to me but does stutter taking to others.
