DON'T GIVE UP!! - THAT GOES FOR EVERYONE!!
Right, just had to say that up front!
The key to moving on to the next level is two-fold -
1. Having the right equipment
2. Having confidence in your ability
I agree with Kieran (as usual!!) try a mini-mal. I surfed for 8 years on a shortboard and got pretty good. I switched to a mini-mal 2 years ago and my ability shot through the roof! If you can ride all the way to the beach, then your board is probably buoyant enough, but it could be that the lack of stability stops you from turning etc.
How hard do you have to concentrate to stay on the board to the shore? If it's more than 'hardly have to be awake' then the board is probably not right.
Confidence is a key thing.
I am way too scared to go out when its like 3 foot lol i dont know why and i am thinking about giving up
If you are happily riding white water to the shore then you will certainly have fallen off numerous times and been held under - hence:
after today getting smashed around and not getting any waves and nearly drowning about ten times i was going to give up
In reality, we all say that we've nearly drowned, but I would think if you're honest, you didn't nearly drown, you got scared by how powerful the sea can be!
You need to find a day when it is about 2 ft and clean. Watch the waves, if you time it right, you should be able to get out back without meeting too much resistance. Once you are out there, you will appreciate the more peaceful side of surfing, you are not constantly battling white water, you can sit and wait. Get your energy back, gain some confidence.
At the end of the day, you know if you fall off, you will survive. My brother in law was out with us at the weekend. He had been struggling in the whitewater for around a year and was also getting fed up.
He went back in the water yesterday - it was 1-2ft and clean, the sun was shining (it was altogether not threatening) Remember a 2 ft unbroken wave is about the same size as the whitewater you have been catching!!
When I left him yesterday morning, he was very disillusioned, but he caught his first 'open face' wave during the day and when I saw him last night he was as stoked as anyone I've ever seen.
Keep at it, your confidence will grow and you will get better.
