Weird hair loss issue

[Eggyolkio]

For the past 3 years, I've been plagued by some hairloss that I find rather peculiar. Since its started, it's never never really slowed down, or even stabilized for that matter, it's just keep getting worse. I'm constantly pulling hair out of my drain, pillow, clothes, etc as the shedding is seemingly nonstop. The entirety of my head has thinned out so much that most of the volume is gone, and I can feel right down to my scalp wherever I touch. In addition to my head, the hair loss has effected the rest of my body as well as I've lost a good amount of my leg and pubic hair, as well as my facial hair noticeably thinner and more patchy. I've seen a few different doctors, had blood tests done and what not but everything has seemed to check out fine? They doctors have varying opinions and cant seem to give me a straight answer, so I'm at wits end. If anyone has any idea of what's going on, I'm all ears. I've posted some pictures with my hair wet that really highlight what I'm talking about.
