You should declare your Islam trusting in Allah Almighty. Allah shall safeguard you from all enemies and opponents. Circumcision is sunnah muwakkedah and one of the signs of Islam. If the armpit and pubic hair grow for forty days or more then it is wajib to remove them. If the name is shirkiya then it should be changed. If the hair of head is in English style (non-Shariah) then it is should also be shaved or cut equally. You should befriend any authentic Alim or Mufti and keep on learning Islamic commandments from him and pass your life according to it. May Almighty Allah give us taufiq to follow the Islam in true way! Amen!
Allah (Subhana Wa Ta’ala) knows Best
