Don't think anything stupid.

First you must put yourself in the proper frame of mind.Then if you face something unpleasant,you can chat with your best friends .You can tell them and ask them walk with you for pleasure.In my opinion,they are willing to help you pull through the difficulties.Then ,music can relax the brain.Always keep optimism

Don't dwell on the past.

1.I think I should take care of my physical health first.Bad health often leads to mental problems.For example,being overweight will shrink people's confidence and weaken their social life.Which results in soliture and depression. 2.Don't always stay at home and siting in front of the computer.Go outdoors to meet friends and feel the nature. 3.Learn how to deal with pressure, getting my life planned and well organized by making a schedule. Hope that helps.,

Well, probably I can help since I'm a nurse here, heh.
