The gratitude I am asking you to express has nothing to do with me.
You have a roof over your head, fresh and clean water to drink, food to eat and clothes to wear. You are receiving medication, surgical procedures, counseling and diagnostic care on the somebody else's dime. You clearly have a few bucks to burn since you can afford to rent hotel rooms, smoke, go bowling and go out to eat. You have not expressed ANY gratitude for what you DO have. Instead you have complained and felt very sorry for yourself.
Do you know how many people die unnecessarily each year in this country because they cannot afford basic health care? Do you know how many people had their limbs amputated in parks with nothing more than a saw in Haiti after the earthquake? Instead of even mentioning you don't have a ride to your procedure you should have said "holy sh*t balls, I am about to get a procedure that will greatly improve my quality of life and I won't have to pay a dime, WOW, I am the luckiest dude in the word!".
Boundaries are not to make your W do anything. Boundaries are for you and your own self respect. There is a plethora of information about setting and enforcing boundaries on your thread and this site.
I am so tired of hearing about your W. I would think by now you would be tired of saying the same things.
You need to occupy your time while you are looking for work. Go volunteer, help your parents around the house or go turn cartwheels in your yard for 8 per day. Just do *something*.
Start to learn the basic concepts of detachment, validation, no contact, boundaries and emotional thought stopping.
Stop asking the same questions over and over again and start reading all the advice on your thread and others.
If you want to talk about you then great. If you keep talking about your W so be it but I won't participate anymore because I am tired of hearing about her BS.
Stop being a drama queen and start being a strong man.
