what is a true happiness?

wow, that is very bad. You will happy if all you need achieved. You will happy if somebody love to you.

Cutepink,
I'm sorry to hear that you're feeling this way. Is there something that's happened to you recently to make you feel this way, or has this been gradually happening? Are you having problems in a relationship or something, friends? money worries? school? Are you perhaps trying to do too much and don't have enough time to finish things? Do you maybe have too much time on your hands and you're not as occupied as you should be, so you obsess about things? I'm just guessing here because you haven't mentioned very much. I find the best things to do when you're lonely and sad are to just keep yourself busy, also try to do the things that YOU enjoy doing. Surround yourself with positive people, exercise, be in nature and listen to the chirping of the birds. You might be depressed and if that's the case, you might want to speak with a counselor or someone. I went through depression myself and it doesn't go away overnight. Today I'm a very positive and optimistic person, but it wasn't always the case. I read a lot of books on Law of attraction, especially the ones written by Esther Hicks, and I found that really helped to improve my mood and appreciate my life. Well good luck to you and hope you get out of your "funk".
