Couple of ideas here.....
1) Do something for someone else, Ie, coach for a winter basketball league, volunteer for a food bank...give something back ( the do gooder in me) maybe you will see that your life is really good after all, and you may become happier.....
2) Surrond your self with friends/family/ loved ones......( I am sure you already are)
3) take a trip......( all for that one)
4) St johns wart combined with another suppliment.....( i cant remember it, but i just heard about it, suppossed to be very good, will find out for you )
The rest I am going to PM you......
