- take a long drive, or maybe take the dog for a walk
- hang out with friends, help you forget about whats the problem
- or just talk to a good friend or friends about what ever is bothering you
I think the best thing to do is talk to someone you really trust with what the problem is, holding all your problems inside makes things even worse and makes you way more stressed out. If you can talk it out, get some outside perspective on the problem it will definitely help you deal big time.
Or perhaps look at pictures of kittehs :3
