Don’t know what to do

My daughter is almost one year old, I’ve just started doing fitness, should be feeling great but i am not. I feel miserable, I’m a single mom, do everything on my own. I don’t eat alot, barely actually. I don’t have the money, nor the time to cook for myself after work, and today is the first time i puked on purpose.

I feel bad for doing it, and I want to feel better, I just don’t know how...
