1. eat right
2. get enough sleep
4. have something for stress release -exercise, meditation, video games, journaling, etc
5. volunteer (if you have time). Losing yourself in someone else's troubles puts yours in perspective
6. take advantage of counseling programs offered by the school
7. don't expect someone your age to be able to help you with your problems - believe it or not, life experience alone is not enough. With age, comes wisdom. ( I can't stress this enough!)
8. Don't take on more than you can handle. Start small and work your way up - course load, job, hobbies, etc.
9. Don't run from your problems. Meet them head-on. If you are falling behind in your classes, devise a plan to catch up. If your finances are strangling you, find a workable solution. Running only makes it worse, later on.
10. Have that one person you can call, any time of day or night.
11. Don't be ashamed or embarrassed. It's okay to go back home if you have to. It doesn't mean you are a failure. This is perhaps the most important of all. I have had two family members who didn't go back home when they should have. One ended up in financial ruin. The other took his own life. There is always a way through your problems. It's just impossible to see it sometimes when you are in the middle of it. Ask for help!
12. Keep this phone number - it is the Nat'l Suicide Prevention Hotline 1-800-273-8255
That's it for now! The fact that you are asking this question means you are already one step ahead, because you are aware of mental health! Good luck!
