Why is this?

[Goose14]

Hello everyone,
So this is my first post on here. And I'm not really sure if this is the right forum for this particular post.
But now that it's 2013 Im trying to get my life together in a sense, and hopefully you guys will be able to help me out!
So my story is, I've always had anxiety issues, but I never really did anything about them until I had some intense experiences such as walking on a bridge, and getting a really strong urge to jump off, now im not suicidal but It's maddening constantly thinking about jumping off and i realize it is just anxiety however it is very scary. The other problem may not seem like as big a deal as the previous, but this is really starting to affect my life. So I've joined and quit this MMA gym twice now in the past year after hardly ever going, and I just joined again a month ago, and im paying 150 dollars a month for this, and I really enjoy it everytime but everytime I want to go, I get really freaked out and come up with a thousand reasons not to. I'll tell myself okay you have to go, you can't not go, and right before it starts I will not go. Infact a class I wanted to make myself go to all day today starts in 20 minutes and I just won't go. Is this social anxiety? Why can't I do this when I really enjoy everything about it, and everything I could potentially gain from it. Please help!

Has a hint of social phobia about it. But what stands out is anticipatory anxiety. That is when we think ahead of ourselves at what might be. If we go here we may feel this way. This might happen or that might happen. Thus we are getting this big build up even before we try and leave the house. Chances are none of this will happen. You would go and enjoy the MMA classes. Most times such worry is all over nothing. But it is a type of anxiety that can stop you dead in your tracks. Get in the way of your life. At best you can try and learn to live in the moment you are at. If you find yourself thinking ahead of time, distract yourself. Find something else to do. To break the chain of thoughts. MMA is a great sport. I don't do it myself. But I am a big fan of the UFC. Be a good release for any anxiety you might you. All about trying to not think ahead of yourself. Live each hour as it comes.
