goddammit I feel defeated

I'm a single mom. I've been helping my folks with their bills since my dad had eye surgery. Just when I kinda almost able to pay for all the bills, my car broke down again. My two credit cards are maxed out. I just filled my car up with gas and now I can't use it. I don't get financial help from my daughter's dad. I have one credit card left.. I'm scared and tired. I feel so fucking God damn defeated, it so hard to be strong all the time. Damn today really sucks.
