eczema, hair problems, & rosacea?

I've been having skin problems since I was an infant. At around age 9 or so maybe younger I had rashes at first at the fold behind my elbows and later on it was also at the back of my knees. My family doctor then gave me creams...some may have changed throughout the years as it got worse. However, I found out later looking up at one of the creams that some side effects were more development of body hair, at that point I have already had less problems with the rashes. For 2 years now none have developed although since at the age of 13 or 14 i found keratosis pilaris or maybe rosacea at my upper arms. I started pinching out white substances from the bumps which in turn became a habit until today still when I'm 16. After a year or so when I discovered the bumps on the upper arm, it came up on my thighs however the first sign it appeared at was at my butt cheeks. Now I see these bumps that are white fluids sometimes over time are harden around my body hairs at my upper arm, lower body from waist and down (butt, thighs, shin, knee, calves) and unsure if it is acne or keratosis pilaris appearing on my back as well.

I had thought that shaving or even just plain pulling out the hair on my legs was the cause of it but it did not explain why it appears at the other areas. With no knowledge of shaving my first attempts were done dry for my legs later on Ive learned to do it wet in the shower or bath tube. I was thinking that shaving and pulling out the hairs caused the ingrown hairs that I got, of which i also started picking at and later it appeared to be keratosis pilaris or plain acne.

These problems were and are making me depressed greatly. When I had rashes i remember getting so mad I would just scratch all the scabs off. Now I would simply become depressed often. During summers I would wear long sleeves and never dresses and skirts out. I do sports and also sweat a lot too. I know I need to stop picking at the bumps but it simply is not disappearing and even just spreading bigger and further. I fear the creams that are given and my mom has even took sandpaper to sand off the scabs on my arm and legs. I dont tell her about it on my butt cheeks. There's also acne on my chest being female I even found the white fluid substance around my nipples. I had blamed the creams for giving me developing more body hairs on me and increasing the bumps to form. I once found hair that wouldn't break the skin because of the bump above it. My habit of picking is leaving marks. As a female teenage these problems are extremely depressing and annoying. I read that they would disappear over time...my rashes did yet for the past 3 years with these bumps haven't decreased, I don't want to wait more years for it to disappear.. This is affecting my health because of my depression especially since last year I notice my weight gain...I was skinny but healthy confident little girl and now depressed at my physical appearance. I want to rid these bumps the brown patches I know have from picking as well as the bumps/acne on my back.

I thought about chemical peels and even laser hair removal, but with my little knowledge I dont know what to do. I know how to stop the scabs by not picking but the bumps continue to appear at the hair follicles. Also I am of Asian descent. There's skin problems basically on my whole body and face(acne) and even acne on my head. I even found the white fluid in my ear piercing when it pinched it because it felt like there was something within it like a pimple. HELPP please!
