Replying to Convince me to upgrade

Yo! I'm looking at trying to pursue this journalism/photography thing as I leave college here in May. As part of that I'm re-assesing my gear. Currently I'm shooting with: 7d (mk1) Rokinon 8mm fish, Tokina 11-16, Sigma 18-200 3.5-6.3, as well as a nifty fifty. Honestly, I really like this setup, Only drawbacks I have hit are buffering when I shoot too many photos and lack of a nicer long lens.

I know I need more glass, definitely interested in something like a 70-200 f4, but I'm also wondering if it's time to bite the bullet and go full frame, maybe a 5d Mkii or something.

Right now I'm at 85% photo, 15% video, shooting mainly action sports and a little landscape. Should I be trying to sell my 7d and upgrade?

Financially I'd much rather spend my money traveling to shoot stuff, is that a bad call in this situation?

Any advice would be super helpful, Thanks!
