Zomby symptoms and conditions

Since being on Lexapro, I have no feelings of anxiety. In fact, I have no feelings at all. I am numb to everything it seems and I have little to no emotion - ever. In addition to being a zombie, I am hungry all of the time and I have no energy to do anything, but rest on the couch. I have been taking Lexapro for about 3-4 years and have gained about 30 pounds. Now that is depressing. I am slowly weaning myself off the drug now. I took 1 pill every other day for a month and now I am taking 1/2 every other day until my prescription is gone. I'm experiencing some additional side effects now. I am having mini panic attacks where my heart will race for about 5-10 minutes, restless legs where I need to keep moving them when I am trying to rest, hot flashes where I will sweat profusely, I'm very irritated at the smallest of occurrences and the most strange side effect that I have not heard of previously is breast soreness - very painful. If anyone else is experiencing the same, please write about it, I would really like to know if this is common, how long it will last and if there is something else (natural) that I can take to help with weaning off Lexapro. Please help!!
