Toprol-XL and depression anxiety

Up to 50mg for supraventricular tachycardia. Also clinically depressed and extremely stressed. Now having more depression, anxiety, mood changes, fatigue but insomnia at night, Also, gross diarrhea and increased ringing in my ears. Somehow, I think it may be better to have the ablation procedure, which I am told can totally fix my electrical rhythms in my heart. Am thinking of it as I already have struggles with diarrhea from ahivng Crohns disease and having a few feet of large intestine removed. Also, lack of appetite, not increase.

I have been taking 25mg generic for about a year. Have had increasing short-term memory loss and beginning to have episodes of slight tremors. I can't correlate this with anything else except starting this med - can these things happen on such a low dose?

have been taking toprol 25mg for only 5 days for rapid heart rate and feel worse on it then i did dealing with the rapid heart rate and occasional flutter. trip to the er told me i was fine. cardiologist and family practitioner want me to increase the dose to 50mg and tell me the following are not side effects though i am experiencing them: jolting surges of chest pain on the left side (never had before taking toprol), nausea and loss of appetite. i also have depression/anxiety, dizziness, insomnia. i hate the feeling of the medicine as it kicks in. they say if i take more i will feel better. they also prescribed and told me to take xanax for anxiety. last night i tried taking half dose to see how i feel. i don't feel better...feel worse. i am afraid i will be on this for life. i just want to be a normal person and feel normal. i can't work, can't function, and my husband can't deal with it anymore.
