Do I Have Ear Eczema?

Well, crap.

For the last two years, I have had dry, crusty skin in my ears that I still am ALWAYS picking at. They are usually white patches of skin but can be yellow occasionally. I always thought this was just dry skin, but I just found out what eczema was, so... sh*t.

I've not only looked into eczema but ear dermatitis and psoriasis as well. I do have many symptoms of them listed EXCEPT I do not have any itching nor does it swell or hurt. It isn't red or irritated, either. However, when I peel off these patches of skin, it does hurt (obviously), gets a little red, and only swells a little bit. But it goes away within the next day. It's almost like peeling off a scab.

The only reason I pick at it is because I'm kind of OCD-ish, I just pick at it for the sake of picking at it, and not picking at it bugs me. I also occasionally have very bad dandruff on my forehead and scalp, but it only happens occasionally. I do NOT pick in my ear canal or anywhere near my eardrum, just in my ear lobe, so I would not have any possibility of damaging my actual ear, and I'm a 16 yr old female.

What is this, how bad is this, and what the hell am I supposed to do?

I will absolutely cry if I have psoriasis or eczema.
