I am not trying to be unkind by saying that I think you are thinking about this in reverse. Becoming a mother is something you do after you are healthy, as children deserve parents who are in a position to provide them with all the love, care, and attention they need. Even in the healthiest person, parenting is challenging, physically and mentally. If you are not in a place where you can do that, where you can give your best to your child-- and honestly it doesn't sound to me like you are, you should focus your energies on your health.

I don't believe that trying to get pregnant should come before trying to get healthy, physically and mentally. However you need to do that-- and maybe switching T's needs to be an option you consider-- that should be your focus.
