Not too sure if this should have a 'trigger' tag on it but eh, you never know..

Had a few problems in my life recently and most of them've been mainly my fault. I've started deliberately and consciously depriving myself of sleep because I feel like I deserve it, but it sort of clicked in my head that it could be considered SH and I've tried cutting down on that recently after around a year of doing it.

Any thoughts on this?
