guess I\'m stressed...?

My rashes have come back; they take over my body when I'm overly stressed. It's absolute hell when I have them because they sting really bad whenever I try to take a shower and I'm constantly itching. The doctor said that it's all spychological so I need to stop stressing myself out. But how can someone just stop stressing out? Escpecialy when I don't even feel stressed out...? As far as I know, I've been fine for the past few days. Not only are my rashes back, but I'm starting to shed hair like crazy and my gums hurt. More things the doctor keeps telling me are psychological.  I also just got one more dear john letter from yet another job I don't meet requirements for. I'm starting to feel like college was a complete waist of money and time because if I don't get a job soon I'm still going to end up at my local McDonalds...I need a paycheck. What was the point of college if I still don't qualify? How can everyone require experience? How does anyone new coming out of college ever get hired? None of this crap makes any sense to me.  Blah! I hate being stressed....
