There are a number of ways I deal with my fears. First is to figure out whether it's a healthy or an unhealthy fear. Unhealthy fears are the ones you can't do anything about. Healthy fears, you can do something about. For instance, fearing lung cancer from smoking was a healthy fear for me. It was one I could do something about, so I did. I quit. Fearing death or lingering illnesses from obesity was a healthy fear. We did something about it--we had gastric bypass surgery.
Fearing death in general is an unhealthy fear. You're going to die. We're all going to die. Getting scared about it is one of the fears you have to let go in order to have day-to-day peace.
The fears you're talking about are unhealthy, not because you can't do anything about them, but because you're not naming them. Your fear is like this smoke screen that's keeping you from seeing what you're really scared of... Gina may be right, it may be rage that you've turned into fear. And Janie's definitely right, that by facing it, you change it. But you can't face it unless you know what it is you're scared of exactly.
I was scared of being alone. Scared I'd be attacked, scared I'd be raped, scared every man out there was looking at me like my father used to... like a cat watching a mousehole. So I drove, alone, to Texas, and then to Montana, and then to Illinois, staying in hotels and motels along the way, making myself swim in motel pools all by my lonesome, smiling and saying hello to men and women at gas stations, in grocery stores, etc. I made myself do it. And I'm not afraid of being alone anymore.
OK, you're scared of riding the bike. Scared of what? Death? Brain damage from an accident? Pick the parts of that where you have options, and ensure all the options are the best you can make them. Always wear a helmet (there goes the brain damage one, as much as you can get rid of it, anyway). Get the training you need to ride the bike as safely as possible. While riding, stay alert and remember that people in cars can't see you worth a damn, so you have to always expect them to do stupid crap.
And, bluntly? I think being afraid of being on a motorcycle is a perfectly rational, sensible fear. When I step away from my car, it doesn't fall down. Motorbikes scare the living crap out of me--the last time I rode one, I left bruises on my brother where I clutched him around the ribcage. I'm really, really OK with never being on another motorcycle. But, like death from smoking, death from motorcycle riding is, in my opinion, a perfectly healthy fear, so I quit cold turkey...
So - take a look at your fears. You're scared of being alone? What exactly are you scared of? Name every single thing you think can happen while you're alone that you're scared of. Face the ones you can. Change the ones you can. And remember that, overall, fear is what keeps us from walking off bridges and burning ourselves on hot stoves--you just have to remain in control of what you fear to the largest extent possible. And, when it's an unhealthy fear, don't let it become the mindkiller... let it go. (Gina - my FAVORITE part of Dune was that particular saying...).
If you're not just rabidly opposed to Buddhism (my mind's so open I fall out of it on occasion... bump my psychic elbows on the pavement a lot...
), here's a link to a nice site called
DealingWithFear.org. Bluntly, meditation makes me want to smack somebody right between the eyeballs, so I don't subscribe to all of it, but it's very calming just to read some of what they have to say.
