I Have Family Members That Get On My Nerves

I think everyone who has a family, has at least one member of that family that gets on their nerves. lol
However, my rant is Mother's Day. I raised my children as a single mother. I was poor, but my kids always got gifts on their birthdays and christmas, Easter things ect. regardless. They're adults, I still help them out when I can, although I'm on a fixed income. I've given them a safe place to stay, if they run into issues. I've traveled miles to rescue them, watched their kids so they could work, given them groceries when they were in a bind. Now, I can't even get a damn card from either of them or take Mom out to dinner. What I get from my daughter is that she's broke and my Mothers Day gift will be late. Funny, heard the same thing for my Birthday in April! How the fk much is a damn card? Oh but ya can buy snakes, ferrets, rats etc...afford to feed them & guess I'm just not important. My son's excuse is, I know ya not much on holidays. Hmph...shake my head. I wonder why? Because I'm always the giver, still always sacrificing & never getting the minimal show of, hey Mom, thanks and we love you. What can WE do for you, for a change? Remember this...the more a person feels appreciated, the more they'll be inclined to do for you. But if you can't show basic appreciation then why should I keep going out of my way??
