Under-appreciated and devalued

I can't shake these feelings of being under-appreciated, so much shit, that isn't my responsibility getting foisted on my shoulders. Though I get a thanks, its so tright and forced it just makes me think they don't respect me at all and are entitled to everything I do.  So demeaning. I just feel so unvalued right now.  I know it's not suppose to be about me, but it hurts to get used so abusively.
