I was just recently put on medication for Anxiety, OCD and chronic insomnia and I also have a history of depression. In conjunction with the medication, I'm also seeing a therapist every two weeks for Cognitive Behavioral Therapy. So far it's been very helpful to me, but I echo the previous posters, seek professional help. Everyone responds differently to the various treatments out there. I'd set up an appointment for an evaluation with a doctor or psychologist and then go from there.
You're definitely not alone in your struggle. We're here to support you. Good luck.
