Why is everything so hard for me???

I just don’t understand the things that I go through. I don’t understand how I’m going to be able to afford to live on my own with my 2-year old daughter. I basically give my whole check away for my daughter to be taken care of while I’m at work. The government doesn’t want to give me any assistance. I’m a single mom. I just don’t understand how I’m supposed to do it.
