A long time ago, when I was a teenager I wore a taweez thinking it was going to protect me and so on. However now looking back on it I know that this is was a HUGE mistake and major shirk. I now would like to do ruqya on myself just in case there might be jinn in me even after all these years, but the issue is I don't know how to read quran: surah al baqara. I know surah el fatiha and ayatul kursi etc, but I don't know baqara since it is very long to recite and I don't know arabic. What should i do?
You can learn to recite it without learning the whole language. You can ask someone else to do Ruqya on you as there is a precedent for it in several ahadith, see here.
