Ups and Downs

I am on a rollercoaster. I like to think I am not depressed, but everybody keeps asking and it makes me angry. After having RAI. I don't feel the same, I don't feel like myself and it is driving me crazy. I feel like I have to over compensate on the way I act so people think everything is okay. But its not, I'm tired, cranky, emotional and very stressed. This isn't me its not who I am. I feel like I don't know who I am anymore. Having an extreme case of graves was never as bad as having any grade of hypothyroidism. Why did I have RAI? It's like I ruined my life with it. The symptoms of hypothyroidism are a lot worse then hyperthyroidism but yet I was talked into getting RAI. What can I possibly do to make myself feel good again?
