Time hit symptoms and conditions

Hi Everyone,
I am a fourth year medical student and recently I started having horrible panic attacks, I feel like crying all the time and I actually feel depressed. I am a "hypochondriac" generally (I guess it comes with the territory of knowing about different diseases out there), but I have been feeling like I am going crazy. I started Yasmin in November of 2006 and I was fine for a few months. Lately, with stress at school and exams, I started feeling like I've just crumbled. I get anxiety/panic attacks (the latest one was at the movies), horrible heart palpitations, nausea, I am sweating, I can't sleep, I feel this knot in my stomach. It's horrible. I thought it was me cracking under pressure, but I was never like this before I started Yasmin. Recently, I was placed on an antidepressant because everyone assumed it was depression, but after reading this post, I really think it might be the pill. I got off it a week ago, so I hope I will see a difference. Thanks guys!!!
