assalamu aleikum, is it hypocritical to still pray when salah feels like a burden sometimes?
Alaikumassalam wa rahmatullah,
No, quite the opposite. Praying when you do not feel like it proves your loyalty toward God: you are able to override your instincts and make your ego perform its duties whether it wants to or not. Umar b. Abd al-Aziz says:
The best good deeds are the ones that one has to force the ego to perform.
