I want to join a military branch, but I don't know which one would fit my personality how would I know?

I know I should just talk to a recruiter, but looking for the public advice lol. Let me explain my personality. I am a very goofy person that loves to enjoy what live have to offer. I can also be serious when need too. Right now in my life I been going through this depress mode and I think its because i'm struggling to figure out if college is right for me or not, but I think I want to join the service. Also how much shape do I need to be in? I'm 5'8 and weight 170 pounds (give or take lol) I'm not fat just a little thick in the right places haha!
