Denial

I continuously put myself into situations that aren't asked for, let alone appreciated.

I sacrifice so much, and for what?

It seems selfish of me to expect the same, but I can't help but feel betrayed when the tables are turned and I stand alone.

You never asked me to do this.  You didn't have to.  That's how much I cared -- I would have done anything for you.

I can't believe this.
