the first answer that i read is on that i truely believe in. my partner has been struggling with dpression and suiceid for a few years and one thing that really seems to elp is music. there are just certain songs that i can start to pick and suddenly everyone is up and feeling a little better. it's not a perminant solution, but it can make things a little more berable for the time being. i also recomed a healthy diet and just getting up and doing stuff. that seems to have made a dramatic difference in the quality of my parter's and my life. keep your own strength up--things will work out in mysterious ways. good luck. your friend is lucky to have you.
