Feeling Out of It

Assalamu alaikum. Recently, I've been feeling like I'm just moving through the day without any spark. I used to be so aware of everything and had this inner drive, but now I'm like a ghost watching myself from outside, stuck. My memory seems to be fading too. I used to recall things in detail, but lately I keep forgetting stuff and drawing blanks. Even in my salah, I forget which surah I recited and keep doubting if I missed a rak'ah. I've got some personal and health issues going on, but I don't know... I just feel like a hollow version of myself.
