/cgl/ - Cosplay & EGL

I've had terrible skin all my life, when I was in 5th grade I got my first cyst. I got bullied a lot and developed low self-esteem, I tried to cover my face with makeup but I got bullied even more because of my cake face. It turns out I had polycystic ovary syndrome (still do) so I need to take contraceptives. I still have lots of breakouts and have terrible skin marks. I've always considered myself super ugly.

I used to wear sunscreen but stopped around 2 years ago, I was heavily depressed after my bf at that time dumped me. He was Japanese so he wanted someone with clear skin...
Now I'm in a healthy relationship with someone that tells me I'm beautiful everyday, the thing is... I'm turning 25 this month, I want to change the way I see myself because even if my bf tells me I'm beautiful I don't believe it. I think taking care of my skin is the first step.
I really don't know where to start, I hate having so many scars, I already went to the dermatologist, but he gave me a tube of Adapalene and that's it. If I go to Sephora they just want me to buy everything they offer.
I need SkinCare 101 advise, moisturizing, cleansing, sunscreen (really? 150 SPF, is that real?) also I'm really afraid of aging and wrinkles (I have very oily skin, but still...)

Yep that's me... redness around the nose, black spots, acne scars, the thing I hate the most is my chin and forehead.

any help? I just want to cry and kill myself...
