It doesn't matter how many chips you have. When you know you have odds like these you have to take them. You HAVE to take some chances in this game to win. Your reasoning is illogical. If you have AA and someone goes all-in in front of you, will you fold? No? Well you are getting worse odds to win there then with your straight against his two pair and there isn't even any money in the pot in the AA hand! I do not see at all why it matters if this is a SNG or not. You can not rebuy in a SNG. Sure you can start another game, but that is not rebuying. Regardless, your strategy should not change much just because this is not a SNG.

Regarding the AK hand. How can he have overcards if you have AK? If what you are saying is there is a good chance he could have something like AQ or KQ, then you should have called here as well. From the looks of it, you are playing a very weak game, and once your opponents know this, they are going to run you over.
