Acne, Hairfall , Insomnia or irregular sleep and greasy dandruff

I have been battling Insomnia for about three years . I think a lot when I lay down to sleep . I cant get my mind to rest or stop thinking. The things I think about are not specific its very random not related to anything. Also I cannot maintain a position that make me feel comfortable to sleep. It has been three years since the problem started and it has been escalated now. I am 18 years of age / male.The acne problem started two years back . It has also escalated now . I noticed after a while that acne used to come whenever I masturbated I tried to cut back but after a while I started experiencing Nocturnal emission . Hairfall and dandruff came about 6 months ago . The dandruff is very greasy and comes out whenever I scratch my head .
I have been taking these meds for about three months

Nat Mur 200c thrice a day for acne
Calc. Sulph. 200c thrice a day for acne

and Nat Phosph 6x four tablets twice a day for nightfall (started only two weeks ago)

I have tried Kali Phosh in the past that didn't helped me a lot for insomnia.
Nightfalls have stopped because of Nat phosph (two weeks is the maximum time for me without nightfall earlier it was a week max) . I haven't masturbated for a while now and hopefully will never . Acne has been reduced a lot though it has not gone completely . Insomnia on the other hand has increased and hair loss has been increased significantly. Scalp has greasy dandruff that gets stuff to my nails when I scratch.
Please advice a new medicine routine for me
thanks
