Staying Positive? In Need of Help

This may be kind of a broad question, but what helps you stay positive?

Lately, I'm struggling with the feeling that things are so out of my control and not going my way at all. It makes me feel powerless, helpless, anxious, and unworthy, because I feel let down a lot from the things happening around me and by people. It makes me feel like, "What's the point any more?" Everything keeps going wrong. I don't want to rely too much on certain outcomes to make me happy, but I'm not sure where a starting point would be as far as being self-reliant.

When you feel this way, what helps you? Any advice would be helpful right now. I'm also wondering if there's anything in particular I should try to stay away from since I'm in a vulnerable state. I thought my self-esteem was getting better, but I feel myself slipping and don't know what to do about it.

I know this might sound cliché, but focus on the smaller things that are good in your life. When I look at life in a whole it just brings me down into the depths of despair. I feel as if I have no control. Sometimes I am just thankful I have a roof over my head and food in my mouth. I have a family that loves me and every day I wake up is a new day. By the end of the day I can feel accomplished that I made it through another day, sometimes that takes a whole heck of a LOT of strength. I always try to remember things can be worse, oh so much worse.

For me I seem to struggle the most when I cannot find a reason for things going wrong. Which is hard, because sometimes life just takes a downward turn for no reason.
When I struggle to find positivity I try to immerse myself in a task, sometimes focusing on doing something that you are good at can be a sort of meditation. I also know that when I am in a vulnerable state I need to avoid the temptation to follow it down. I will tend to want to watch sad movies, listen to down music etc... I have to try to remember to act the opposite.

Hope some of this helps, I am kind of rambling, am also a bit off myself.

It does help. I was also thinking that maybe I should try to look for some uplifting music. Sometimes it's hard, because I crave music that's on the dark side, especially when sad. Even though it can comfort me, too much of it might be draining. So maybe I'll do some searching. With TV shows, I'm definitely better at finding upbeat, mindless, funny shows....maybe it's a start, although boredom can be a problem for me. At least work will keep me occupied tomorrow, although I swing from wanting to call out from all the pressure, but avoiding staying locked in my bedroom would be a better choice for me. It's still so hard to fight these feelings though. Sigh.
