What is the best way to improve rhotacism without proper speech therapy? - speech therapy more condition_symptoms

I am 17 and have never been able to pronounce my R In general, they look so, W and L's. I went to speech therapy as a toddler, but I do not know. If a person exercises at home, it simply would like very expensive speech. Thank you!
