I'm trying so hard to change and to improve myself....I try to think positive and to stay away from stressful situation....

I've been going through so many challenges in the past year and so....and I'm still alive....I don't want to go through them...as I want to put them behind....

Past is gone...Past is dead...and future hasn't arrived yet....I want to live in present and I try my best....but I need your idea, your help...

I know the key to success is trying hard and try different ways....but how?

Give me some ideas....how to change? how to stay happy? how to sleep comfortable at night? I can't remember the last time that I went to bed and slept good....and I know what the problem is...my useless thoughts and stress over being lonely and getting old....then I can't sleep at night....I'm afraid to get to bed and have all these thoughts.....how can I fix it?

thanks a head of time....you guys are awesome....I'm so glad to be here...
