Yes, you have an excellant reason to take good care of yourself. You, and your child. There are many avenues of help out there, start with a check up, see if you can clean up your diet, exercise, re direct your thinking, anything that will make you feel better. When we feel physically well, the mind tends to follow and vica versa.
I hope you can start making the effort to be well, it is work, but you are so worth it!
