Life is DEFINITELY worth living. There are many dark moments though. I am going to tell you what worked for me. I was never suicidal but I was pretty depressed at one point until I made a commitment to be a more loving person. What does that mean? It's all about the little things...smiling more, saying hello to strangers, make a commitment to be a better listener, be non judgemental, be a more giving person (not just money but you can give your time to people just by listening to them). Choosing a charity would help too. I am involved with Children Incorporated. It's like $25 a month or something like that but I write letters to my child in Africa and I know atleast I'm making a difference in someone's life. There are so much more you have to do to be happy than just "be a more loving person" but if you love others, the love will come back to you. Make a commitment to be a more loving person and you will see what happens. There's also a lot of little things you gotta do too...Are you getting any exercise? Just try walking 20 minutes a day. Get enough sunlight. Make sure you drink enough water. It all starts with love though. And you are capable of it. Now just start NOW!
