Do i have a disorder or am i over reacting....?

You're depressed, which can cause panic attacks. Which sounds a lot like what you're feeling. I am sure your medication doesn't help that and OCD is only going to make it worse. The shaky hands, the dizziness, the irritability, thinking you're going to go crazy or are going crazy, thinking things are pointless, it as all signs of either depression or anxiety. Try to figure out why you are depressed/anxious. It can be solved without medication, but if you cannot find respite. Seek the help of a therapist/medical professional. Try to clean up your diet, that sometimes helps. Dairy, glucose, sugary/salty foods have sometimes caused this in people. I can't tell you why you're having this problem, but explore the options of recuperation.
