I had a similar experience too.. went out at the local break the other day and it was a washing machine, currents going all directions, never been in anything like it. came in after a couple of waves, not good at all

great advice from people on the forum. as jaffa said, if you're in australia look into a lifesaving course- it'll give you more confidence as well as better skills. not sure about other countries but I know aus has an awesome lifesaving program.
what I did is have a couple of surfs in smaller waves where the currents aren't so hektic to get my confidence back to charge the bigger stuff. not to mention always surf with someone else, it can get nasty fast in the water so it's good to have a friend there, you'll feel more comfortable, + someone to add legitimacy to your bragging later haha!
sometimes when I've spent heaps of energy paddling out I'll wait behind where the sets are coming through and just sit on the unbroken swells to have a breather. don't just rush everything if you dont really have to, it's just a recipe for a fast wipeout and another long paddle back. wait till you have some focus.
ultimately, you don't want to regret anything, but there's a line between going for it and being plain reckless. get out there as much as you can but don't put yourself in bad situations, you want to surf another day. but these guys have given awesome advice, if you do that you should be able to charge stacks. I dont know how those big wave guys do it, far out. I like my oxygen
