My first week of Cymbalta after switching from lexapro!!

OK so after having an anxiety brake down my doctor put me on cymbalta beause lexapro was not working for me and going up the medication dosage just made it worse. I have GAD , Ok this first week the first 3 days that i quit the lexapro i felt better heart palpitations were gone in the morning, I had just panic attack intents and all this week I had just 3 big panic attacks but they were caused by OCD thoughts. the on edge sensation is gone and now i can sleep!!. But ok the anxiety is still there and when i wake up i have nervousness. This last 2 days the heart palpitations came back i hate it because it makes me very tired like almost fainting , and yesterday out of nothing i had a panic attack because of an ocd thinking, I have going crazy,harm pure ocd. The doctor put me on 30 mg so i was wondering if probably he would have to take the medicine up ? this pill doesn't give me horrible side effects i feel kind of a little better than with lexapro, i still have a lot of panic and anxiety but somehow i can do everything go to school , work and etc. I want to feel normal and i am doing all i can like i am not checking anything whenever i get ocd thoughts like " what if that what i just heard is a hallucination?" instead of checking what i am hearing i just try to think yes i am crazy is ok!!.I know it sounds stupid but if anyone here had OCD , you would understand !! I am still trying to find a therapy but its hard to find it with my insurance!

Thank you for helping if anyone has had any luck with cymbalta for ocd and GAD please share it with me !!
