OCD of pure o. Tablet ie beta one xl 40.

I'm suffering from OCD from teenage I have taken clofranil 25mg at teenage for 1 to 2 years I felt good and stopped . This tablet really worked and my mood was good and happy but The side effects I used feel missed heart beat and if suddenly stand up used feel eyesight going dark for second or 2.   OCD episode reoccurred in adult stage at age 28 I consulted doctor and was prescribed Revilife 100 mg took for 1 years while during course of tablet I was diagnosed for high BP and physician told me to stop psychiatric drugs and prescribed Atenolol 40 mg and I kept on taking this from age 28 . Now recently from 5 years back tablet has been changed to Beta one xl 50 . Now presently from 1years I'm getting  extremely pure o ocd kind of obsession and compulsion. I'm taking clonazapam MD for pannick . Please Doctor suggest me some medication for OCD thought control which doesn't has side effects related to Blood pressure and Heart and which doesn't collide with my Bp tablet ie Beta one xl 40.
