Ok so well i switch my car to synthetic oil both the engine and the gear box. Well first the engine. It has 60k miles on it i heared if you switch to synthetic after that it might start leaking so i tried it it didnt leak. Next Gear box oil change i put in syntehtic about 2 days later i noticed a little pile of clean oil under my car im like WOW what the hell. Now about 1-2 weeks later the puddle is bigger. And i checked its leaking out of my gear box but its never leaked before in the past 50k miles. So did it start leaking because of the synthetic oil and if so if i switch back to normal will it stop or now thats its leaked its opened up the gaskets or seals or whatever to the point where it will leak no matter what and im screwd and need to find em and change em? sorry for no punctuation.

Also i think im really screwd i switch to synthetic oil in my engine. Now i think my head gasket is cracked cause of the white smoke and stuff. And if i switch back to mineral might there be a slim chance that mineral oil cant like get through the part where the synthetic did and my head gasket would get un cracked lol. So yeah im guessing im pretty screwd i should switch back to mineral on both now before more problems start right?

It seems to me like you already have the problems that you are going to have. Assuming the car is running OK, I think the smoke is oil leaking past the valve stem seals. New seals (sometimes easier said than done) should cure the leaks and smoke.
