Question regarding Skin/Hair

Hi everybody, I have a question regarding my skin/scalp. I’ve gotten rid of this stuff from my body before however I got reexposed due to hvac issues. Because of that I got into a habit of wanting to “Clear” this stuff out of my skin and scalp. I used to have such long thick healthy hair now my hair is much shorter and it feels very rough around my hairline. Sometimes I just cry when I look in the mirror because I used to have such clear skin. Now I feel like a monster sometimes. :( I have heard that daily borax baths are helpful for this condition but I am worried that my hygiene habits are too much and i’m making everything worse. I want to just feel like a normal girl again.

1. For those who have beat the condition, is it possible for my skin to clear up by just clearing out the infection from the body internally? Along with that, I basically have ingrown hairs/chunks of hair that are hidden under some type of film… That is what bothers me and it feels so rough and it’s painful. However If I just focus on clearing my body out from within instead of externally, will all of that nasty stuff go away? I feel so bad being rough on my skin trying to remove this stuff but it bothers me knowing it’s “in” my skin. Like I said i’ve gotten exposed to this before but I never had such bad acne/hair loss like this before. Not only that my face sometimes looks very bloated. I am just hoping to have some type of faith or something to look forward to. I used to be able to keep going with my life but as of recently I feel so depressed like my skin will never clear up and this nasty stuff will be inside of my body and scalp forever.
