I never wanted to resort to tanks because from what I've learned they're heavily looked down upon
We've now gone full circle and we're back to the plain and simple fact that your problem is you. You're bothered what people think of you so you won't leave a session when people grief you, because you have it in your head that it will please them in some way. You won't use a tank because other people look down on them. There's nothing you can do in this game that doesn't get looked down upon by someone.
Seriously, next time it happens just swallow your pride (it'll hurt because it's clearly very large) and immediately walk over to your console and power it off. Don't mess with menus or faff with "should I do this, or that, or how can I show them!" - just turn it off. Then, turn it back on and start a new game.
Try it. At least try it. You'll see that it doesn't matter to anyone other than you. If you can't take this advice then I don't see that this is a question/discussion thread. If you can't do that one simple thing (and it is so, so simply) then this thread has no meaning.
