WTF?! Transmission Problem?

[Grip72]

Ok...i hate my life and my car is stupid.

I went to get groceries at safeway and there was a tiny patch of ice and my tires spun in first gear....all of a sudden, my car won't engage into ANY gear, not even reverse. It just makes a sort of soft grinding noise. (so of course i cus, etc etc) I manage to push my car into a parking spot and try it again. This time it works fine! So i go get groceries and when i'm leaving the parking lot, it does the same thing and this time i'm fuked!! So i push it into a parking spot and gather my groceries into a shopping cart and push them home, 2 blocks away...ANyways...is my tranny hooped or what?
And if so, how much does it cost to fix/buy a new tranny for my 91 Honda Accord 5spd?
