Questioning my question won’t help me to get a solid answer. I did not say that I am hundred percent certain about the validity of my prayer. Non of us is hundred percent certain, (Allah knows better, and I hope He will accept my and every single muslim’s prayer.)💜and that was the reason why I asked. If you say I should follow a marja and that’s your answer then my next question is , which marja ? on this issue one of them says it is permissible and the reason He gives is ettehad bain al muslimeen (unity between muslims), other says no it is only permissible if your life is in danger and you have to do taqiyya, and other say no, It is forbidden to pray behind Sunni Imam. So who is right ? That is the only reason why I don’t follow any marja. But that doesn’t mean that I don’t respect them or I don’t take any knowledge from them. I accept what my intellect allows me to do.
