Dents and thoughts

I developed two dents on the front of my scalp last year and they peak and trough in terms of indentation depth. I’ve also noticed more devits appearing around my scalp. I had an extremely difficult time yesterday and didn’t sleep last night at all. When I got up and looked in the mirror one of the dents has doubled in length overnight and now runs vertical on my forehand up into my scalp. It looks like I’ve been glassed or suffered some sort of contact trauma. Does anyone have a clue what the hell this is and how can this appear from nowhere? To note my muscle loss, loose skin and masculine depreciation has continued to worsen…
