Turbulent twenties

I have been stuck in this quarterlife crisis for a good while now, and it is by far the WORST phase ever. Even worse than adolescence, and that's very telling because my adolescence was quite shitty. The doubts about the present, the uncertainty about the future, the nostalgia of the past... it kills me a little bit everyday. I'm the most successful I've ever been, but at the same time, I'm the most insecure I've ever been. It's hard being pushed and pulled between feeling content and feeling insufficient. It actually peeves me when people tell me I don't have anything left to worry about. Life is not all about school and getting a career. Once you have a career and are done with school, the only thing left to think about are marriage, kids, and possible relocation; I am consumed with fear and anxiety thinking about the future. Everyday. Literally. There are times when I am convinced McAllen is a black hole sucking the life out of me. Things are different. I sacrificed some aspects of my life in attempt to gain something in other aspects, but there are definitely times when I just feel like I am losing all around. Ever since I moved here, my flaws have become so much more pronounced, and they are interfering with everything. I feel suffocated by the fact that I am trying so hard to suppress these negative feelings, yet they keep coming back like vultures. I've debated going back to school in a possibly fruitless but ambitious attempt to keep busy, develop hobbies, gain more knowledge... but on second thought, going back to school is useless. What the hell would I go back for? I don't want to change my career; get a PhD; get a second masters. There are definitely days when I just want to pick up and leave. But then I think.. I can't just leave my job. I don't have enough money. I'm just not ready. So yeah, pipe dreams.
