Horrible acne, never has been this bad I'm 24?

Hello, I have never in my life had acne this bad. Since spring it's been on and off in terms of how much acne. Lately its been so hrorible. My face will not clear. I think it's stress related, since my ex told me when I said "dang I am so ugly" that I have "a little acne but you could clear it up with some thing like Pro-Active" I was so disgusted. I know it could have to do with what he said since I am so sensitive to the way people say certain things. He also said some other things about my looks that just have ruined my confidence. How can I just move on from this stress. I've been eating well, better than I have ever. I don't know but what may have started it is that I was using some oil on my hair, when I slept with it in my hair I had a break out very icky. That was almost a year ago. Now I have itchy pimples that either go away and come back or just don't really go away. I am annoyed using Clearasil morning and night. My mother still does she irritated that she does as well - she has even been through menopause. What is going on...... Please some real advice
