I was diagnosed Anxiety disorder since 2017.
Got a severe headache. Brain fog, lightheaded,  tight headache.

The serious problem now is i always feel tired in day time, if i wake up early despite enough sleep.
If i got nothing to do, i can sleep longer. Also causing tired after wake up due to active in brain in bad dream.
Because of that, i suffer memory loss, focussing, learning ability.
If i successfully change my sleeping habits, will my cognitive impairment can be recovered?
