I play sit'n'goes at 2+0,50$ and the opponents in my games frequently goes all-in.

I feel like I loose credebility when I do a raise with a real hand and someone raises me all-in making me fold. I mean, I don't like to gamble and will only call a big all-in with my very best hands.

I think theese guys will see me as weak even though I was the original aggressor and start using this as a strategy against me.

What to do?
