I'm suffering from low spirituality since many months now. I don't know if it's because of my self which needs spiritual purification or my surroundings. I'm living in (Location removed) where there's no one I know who's a Shia and my parents too Non-Shia. I'm in taqiya from all. But it didn't matter during the first year of my reverting. Why then now I'm facing difficulty? If it's due to lack of spiritual purification then could you tell me the steps I need to follow in order to get purification

Definitely sorroundings have effects but you have to check your routine.
Do astghfar 100 times after fajar. Spend some time on prayer mat just examining your self.
Do tawasul with imam e zaman ajtf
