How do I live with ADHD without taking medication?

I don't have health insurance and have never been diagnosed with ADHD. Mostly because when I was younger my parents didn't believe in stuff like that and either did I. I thought it was something you just delt with. But now that I'm older it's affecting me on a very serious scale. Here are things I deal with on a regular basis.

I rock, back and forth, when I'm seated. I can't sit still, and it's something that calms me. I look like a crazy person but I don't even realize it unless someone points it out. I just cant sit still. I'll be at a friends house with my shoes on and a backpack and walking back and forth while everyone is seated and I constantly get asked "are you going somewhere?" I'm not. But I just hate to sit. I get anxious, It's like turrets but instead of blurting out things I just have to move, always. People even tell me I make them nervous but I don't even realize how awkward I look.

I get bored often. Always. I always want to do SOMETHING and when people I'm with can't figure out what we're going to do I just get frustrated. I also have a "one-track" mind. Meaning if we finally figure out what we're doing I'm 100 percent commited. But if we are on the way to do something and someone suggests something else I get irritated. It's like we FINALLY decided to do something, we are on the way, and now you want to do something else?? It drives me crazy.

I also have modes where I turn everything around. I make goals and plans and I do them, but it only lasts for about a month before I get bored with it. I start slacking or doing other things. Even with new jobs. When I get a new job I'm there early for like the first month, working my *** off. But after that month I start showing up late, or taking off. I go from excited to literally dreading it. Like I'd literally do ANYTHING else than go to work. And when I'm at work I find myself going to the bathroom like 20 times. Just to relax. And I feel soooo tired while I'm at work, but as soon as I get off it's like I'm energized again.

I feel like I'm lazy, but i'm not. I'm very dedicated when I put my mind to it. And what's worse I KNOW what to do, it's just so hard to drive myself to do it. I stay awake at night making plans of how I'm going to change it, but when the day starts I'm so exhausted. And it frustrates me to no end.

What do I do? I don't have health insurance, and even when I feel like applying for even that it's hard to drive myself to, especially since I'm also bad with money. Go figure. I'm driving myself insane ... INSANE. Help? Anyone? Thanks.
