Where to go, what to do?

I have no idea what I want to do for a living.
I did not go to college right after High School, I did not have the money.
There are things that bother me on a day-to-day basis. I think about a few things, 100 times, every day.
1) I regret quitting Football. I loved it so much, I should have never walked away. I am hoping that there still might be a chance for me to play, however I would have to do massive working out for the next year straight.
2) Kaitlyn, The girl who I obviously cannot get off my mind. Things felt like she was the one. And she wasn't just a "thing," I had known her since 1st grade, and when I looked back on how my ideal girl and it matches her to the fullest. Not one thing is missing. Erg.

Anyways, I have issues.

I was trying to figure out what I want to do because I can't sit around any more.

Options
- Extreme Work-outs for a year and then go attempt to try out for a football team.
- Join some branch of military, if they would even accept a big shit like myself.
- Get a full-time job.

And I don't know any other options.

Go back to high school for another year.

I couldn't do that, I graduated. :|

I graduated and I'm going back. My sister graduated and stayed for 2 and a half years extra.

Well, I do not have that kind of money at the moment.
