Car engine light came on. I can’t take this anymore

Windshield wipers have been broken for months, it would be $300 to fix (pipe dream), it’s almost $350 a month for payments and insurance, it’s a huge gas guzzler and I rarely can afford more than a quarter tank at a time, and now this. Who knows what it is, the engine or anything else but I just know it’s going to be bad. I don’t even like this damn car and I don’t need it anymore because my whole life plans changed 6 months after I got it, so I’m just ready to drive the freaking thing off a bridge. Can’t even afford Christmas gifts, and now night not have a car to drive. I don’t know if i can keep doing this
