What is going on with my skin?

A while back, I got Pityriasis rosea on my leg. It didn't bother me and it went away on its own. After a few months, I got red, flaky, itchy, burning patches on my cheeks. Nothing really helped and I applied a lot of moisturizer to keep them cool. Some things made it worse, then it would almost completely disappear and then it would appear again. Eventually, it went away but I still have slightly enlarged pours on my cheeks and they are still always pinkish just without the red, flaky, burning part. I went to a doctor and she didn't see anything because on that day they weren't there and basically everyone ignores my problem. I've also begun blushing easily like from heat, exercise, alcohol, smoke, etc. No one wants to help me. I don't think it's rosacea or eczema, at least not now, because it's not that extreme. It just looks like healthy rosie cheeks but I am not healthy atm so it can't be that. I don't get enough fresh air or exercise and I'm under severe stress.
