Anyone else feel defeated in their career choices? (Merrillville)

Does anyone else feel this way? It’s like no matter what I do, I’m met with resistance.
I don’t find my job enjoyable but I struggle looking for gainful employment.
I’ve debated going back to school but I’m not sure how I could afford being full time as a student.
I know it’s not right to give up and I make decent money now but what’s wrong with wanting more out of our career choice? Does anyone else feel like their potential isn’t being fully utilized?
