i'm tired

I'm in a really big resentment today. Is PMS making things feel worse than they really are? Maybe, or maybe not...either way I feel totally angry....on top of this pounding headache i've had for atleast 3 straight days, and this feeling of total exhaustion.
I wish I could just crawl in a hole....but I can't and so instead i slept most of last evening away and most of today. I'd still be sleeping but my work cell phone woke me up. It was the administrator of the nursing facility I work for. I didn't answer the phone. I just checked the number to see who it was that called. I was on call for 7 days......my oncall status ended yesterday at 5pm.....and this is my weekend off.....so I didn't feel obligated to answer his call.
So why am I in a resentment? Well for 1 thing the grass in the back yard needs cut. I have 2 sons who expect me to be at their beck n call.....both who have the weekend off from any real responsibilities, and it will not occur to neither of them to get off their asses and cut the grass.............and then there's the bathtub....last time it was scrubbed was when i scrubbed it....doesn't occur to anyone living in this house to wash the damned thing out cept for me......same as the swimming pool...my yard is surrounded by trees and so the pool needs to be rid of leaves everyday....unless I do it, it doesn't get done......
I'm tired. I sometime feel like the weight of the world is on my shoulders. I lie in bed at night thinking of all the things that need to be done/fixed around this place.......and I guess I get in a resentment cause I feel like i'm in it alone...is anyone else thinking of what needs to be done....just once i'd like for someone else to say "i'm going to take care of this, or i'm going to take care of that"...and I just wish they would, without depending on me to orchestrate the whole thing, or without me having to ask........I don't know what's bothering me. I haven't had a vacation in 5 years with the exception of a few long weekends....I've cashed them in for money, and then last year our company was sold and we lost our vacation time......maybe i just need a vacation? Maybe I need to laugh and have some fun? Maybe I need a good long cry to help get rid of some of the stress i'm feeling?.........just wish this knot in the pit of my stomach and lump in my throat would go away.........and why was the admistrator calling me? It's my day off...I think it's rude he would bother me on my day off....I just finished 8 days with a day off and 7 days oncall....he should not be calling me! How much does a person have to give before enough is enough? I shouldnt have to give that place a thought on my personal time. If he calls back, i'm going to ask him to come over and cut my grass or scour my tub.
