Coming off of metoprolol?

About the middle of April, I had been on 25mg twice a day of metoprolol for about 3 weeks for hypertension. I felt fine until I started getting blood pressure spikes of up to 170/95. I was then put on 12.5 mg of hydrochlorothiazide in conjunction with the metoprolol. That brought my blood pressure too low. A month ago I got stepped down off the metoprolol and have been completely off since June 29. Since being off I have had heart rates at rest of high 80's to 100 bpm. I feel weakness in my chest, I tire easily, and feel the need to take deep breaths more often and yawn alot. Are my symptoms going to ease up? This really brings my anxiety level up, and I am actually on lorazepam for that too. Anyone been through this that can tell me what is going on?
