Why is white smoke coming out of my exhaust an didnt really want to start to make it home but did

I don't know that's y I'm asking now

Is there a smell of coolant with the white smoke? if so you may have a blown head gasket or a cracked cylinder head.

Your only hope it to pull it apart and look only then can it be determined if it's a head gasket or the head. It's up to you if you think it's worth repairing, you can do loads of damage driving a hot engine it may not be worth repairing.
