Geez, that's harsh, uss.

Is your party REALLY 1st level?? If so, there is NO WAY you should randomly encounter 4 Frost Giants. And it sounds like your DM is a bit excessive on the NUMBER of random encounters.

I don't know all the facts, but it definitely sounds like you have the toughest monster in the entire AD&D universe - THE KILLER DM!.

It's a no-win situation because there is NO WAY to beat the DM if he doesn't want you to. With the situations your running into, I would say you definitely need to play some kind of fighter or maybe a fighter/mage multi-class. You need hit points and armor, from the sound of it.

The fighter/cleric was a good idea since you could heal yourself.

I hope things improve for you so that you don't end up hating the game.
