I guess what I'm wondering is why you want to go back on ANYTHING?
You stated, twice, that you don't feel stressed, and you said nothing about feeling anxiety, panic or depression.
Since your tests all came back normal, your heart is fine. You say you have some concern that they missed something, which is highly unlikely. What did the doctors say about your "slight chest discomfort" and abnormal heart rate? If it was anything to be concerned about, they would have ordered more tests or sent you to a cardiologist, but they didn't.
You have some MILD anxiety about your chest discomfort and HR and the possibility that something was missed on your tests. Why not just see your doctor again and have him/her go over their findings with you. I think you may just need a little more reassurance that everything is OK. If you're still concerned about your symptoms, you could discuss it with them at that time. If you can possibly avoid going back on medication, that would be great!
But if you can't, there are other meds out there that will not cause weight gain.

I am not sure on what pills will cause weight gain and ones that won't but I am on citalopram and I have not gained any weight and since I started having anxiety problems I lost twenty pounds but I think thats because I just didn't feel like eating.
