Watch Out... Big stack!

I seem to have the worst luck in poker. And when I say that, I am not really talking about starting hands or suckouts, I'm talking about being surrounded by big stacks! So enough is enough, and I want to hear any advice ppl can offer in this situation.

My question is three pronged:

What do I do when I have a big stack to my right? to my left? or what if I am sandwich between two?

In all of these cases these big stacks are loose, aggressive, particularly the "phantom" chip leaders we always see in online MTT.

I am aware of the "opposite poker" strategy, but with many of these tournaments having rather quick rounds of blinds, I feel that more times than not, I get bled to death, than find a premium hand to put a big dent in these types of opponents

I don't know what "opposite poker" is.

loose agressive to your right - re steal more.

loose aggressive to your left - find a hand. steal more from EP.

Loose aggressive bigstacks are like the bullies at school. When you run into them, you can't be half-hearted about your hand. Like the school bullies, they are expecting you to back down to their show of force. Either stay out of their way (and wait for a monster hand) or be prepared to play your hand all the way. At some point you will have to make a stand. Reraise AI preflop with middle pairs or AJ type hands or push to their continuation bet on the flop with hands like TP poor kicker or even middle pair. Make sure your stack is big enough to get some respect when you try this.
