Should I have the car fixed or is it not worth it?

I have a 12 year old car that looks quite good on the outside. I have had it repaired many times since I got it just over a year ago. I don’t think the previous owners took much care of it. I drove into a pothole 2 days ago and the damage looks bad. I don’t think I should bother with repairs. There is NO way I can afford a new one right now. I don’t know what to do. If I end up paying more for repairs than the car is worth…..... . Point is that I need a car. I don’t use it to drive around having fun, I need it for work. I feel like going to an emergency room right now(along with all my other problems) and going into surgery to get my heart removed!!!!!! Strange how things spiral out of control when things go wrong. One thing follows the other!!!!
