Why is it so hard to choose being strong and rightous over being weak and drowning ourselves in negative emotions?

Thats my question.
People look at me like a happy person, and I am. But thats only because I fight like hell to be a happy person sometimes. If I didn't try my best to be happy, I wouldn't be. I didn't always, and when things are hard I feel easily weak. I want to go back to old [terrible] crutches I used to rely on. I see myself as a insignifigant, guilty child instead of powerful, strong, and full of life and things to give.

So what do you do?

Thats my other question. What do you do to turn the weakness into strength? The sadness into optimism? Fear into hope? We cannot deny ourselves these emotions. Nobody never deals with negativity. Do you tell yourself something? Make art, music, ext? Something else? Or just feed the negativity because its easier?
Well, I'm trying to not feed my negativity, because it will surely turn into a full blown waste of living. So I guess it is a struggle we all have to fight, but how do you win?

Oh man, I haven't been on here forever. So...

1. Thank you for all the comments, and favorites. I want to sit here and say thank you to everyone who gave me credit for all my crappy artwork, but people probably don't even remember commenting/fav'ing at this point lol. So I will just say THANK YOU! here.
2. My old artwork is god awful. I am trying to clean it up, and put up my new stuff that I have got together over the summer and now.

I've been face-booking my acceptable pictures, but I miss this place because it's more of an open canvas. Theres art to look at, better feedback and its actually meant for sharing art.

My summer was so rad. I've been kicking back with friends, relaxing, and back with an old guy I've had a crush on since I was like freaking twelve. By no means has the start of my senior year been good. There's been deaths in my family, and just a lot of stress. But all grief must cease (Does that rhyme? I dont think so, but its gonna be my mantra from now on because it's catchy.)
I'm really going to start submerging myself back into art and yoga. I am even thinking about belly dancing classes too. I'm going to start putting away money and get back to focusing on my body, mind, and soul. Not shopping all time.
