Forgetting during the prayer

Asalam alaykum everyone I am suffering from brain fog, and so I am very forgetful and it is very hard for me to concentrate. So when I pray salat, I am always forgetting. For example, whether I recited surah fatiah completely, how many rakahs I prayed. This is why I am constantly repeating each salat twice or more and that is very difficult for me. Is there anything I could do to help fix my situation? I think it is probably waswasah, but I do not feel strong enough to fight the waswasahs.
