If you are feeling like no one is appreciating you right now, it's not because you don't deserve praise: it's because you are not demanding it loudly enough! Your ego isn't something that grows on its own. Instead, you have to nurture it. And sometimes, you have to fight for it. Ask for that raise. Remind people of the good ideas you submitted: you know, the ones that made that project such a success? You can't wait for people to notice your real worth. You have to promote yourself more boldly.
