Hi Yankeegirl,
I'm 26, spastic diplegic as well. I walk independently around my house, and use crutches outside. CP changes as we age. I feel it too. I depend on a wheelchair more and more these days.
I haven't had the surgery you had, so I can't really help you out there. The staring sucks, but it's something we will deal with for our whole lives. Maybe it bothers you more right now because of the extra stress from recovery? When an intervention changes the way we move, it can really put us on edge. I recently went into AFOs for the first time in my life. Although my doctors think my walking is much improved, I think it's worse. My balance is terrible, and I'm tied to my crutches in a way that I wasn't before. When I first transitioned into AFOs the staring bothered me too, moreso than usual. Don't be afraid to give your body the time it needs to heal. We take a little longer in that department. It's frustrating though, when all you want to do is get back to work and to your normal life with friends.
As for driving, I'm assuming you don't use hand controls? I've never heard of a diplegic who could drive safely without them, so if you can, kudos to you! Maybe you should look into them so that you can drive while recovering. I'd go stir crazy if I couldn't drive, and I'm sure that's adding to your stress. I don't know if your abductors will ever have the same strength that they did before the surgery. Unfortunately, muscle weakness is a crummy side effect of these surgeries. I've only had my hamstrings lengthened, and they are very, very weak. I had that surgery done in '87.
When the stress of CP gets me down (as it has been a lot lately), I find that stretching, meditation and swimming all help. I find myself thinking more about CP these days than I ever did before. I try to remember that I'm still the same energetic, fabulous

20 something that I was before CP started kicking me in the butt, but it's hard some days. Above all else, be gentle on yourself, and don't be afraid to seek out a counselor if you feel you need it-- I did that a few months ago when I had that same "scared to death" feeling that you describe, and it helped greatly.
Take care,
NJenn, aka Nicki
