Lisinopril and generalized anxiety

I was prescribed Lisinopril for pre-hypertension at 10 mg a day. I've only taken it for 2 days and have felt so sluggish and tired but revved up on the inside at the same time. Had a headache too last night and blurry vision. It does work in lowering the BP though. Last night I felt as if I couldn't take deep breaths to relax myself and then I started having shaking chills and tingling in the hands and feet. Thought I was having a panic attack so I took my clonazepam. Then I felt like I'd have to throw up or go to the bathroom to get relief. The clonazepam kicked in after about an hour and knocked me out, but I still woke up a few hours later still feeling extremely anxious even though the clonazepam was still in my system (I take it twice a day for panic attacks) along with Lexapro for depression/generalized anxiety. I'm refusing to take any more of this drug. I will lose weight and exercise and eat healthy just to avoid this drug.
