I think it's awful to speak so terribly about parents who are actively helping you maintain a "nicer" roof over your head. Talk about biting the hand that feeds you. Jeez. You are luckier than most, you should be thanking them everyday. And if you don't want their help, stand on your own two feet, get them out of your hair, and quit whining like a little girl.
I know this gets me so upset and just sick to my stomach! My father died when I was 14 and my mom when I was 23 and I just can't stand to see people take their parents for granted like this. I've missed them so much, I've needed them so much all these years...it's just difficult to deal with sometimes so I hope the OP can read this and maybe appreciate them a bit more. You'll miss them when they're gone.
I don't mean to sound disrespectful to you, but not everyone would feel crushed like you are when their parents are no longer among the living.
This doesn't invalidate ones respect or love for their parents in any way or means we take them for granted as each person has a unique relationship with their folks ... and besides, it's a part of life.
As for the OP ...
I sympathize with your situation, and my personal suggestion would be that you talk with your parents openly about this, even if it causes some issues.
Do you know what I thought when I read that your mother was close to tears when you spoke with her about this subject?
I thought she was trying to make you feel guilty in order to drop the subject and have it her way.
I'm sorry, but parents have a tendency to do this, and despite how emotional they can get, you must be firm in order to get your point across because at times that's the only way they will understand.
One other thing ... just because parents provided a certain amount of things for their children does not mean the children in question should be kissing their feet at every turn.
Give me a break.
The parents were the one who WANTED that child to begin with and it's their responsibility to care for it and help it.
Being grateful is one thing, but to use this to the degree where the parents EXPECT of you do be 'respectful' of them at every turn even when you are an adult and clearly have other responsibilities that are of higher priority ... then the parents are acting unreasonbale, especially since they are NOT treating you like an adult and don't allow you to live your own life.
You have to force it down to them that you are a grownup and not a kid.
Any parent that treats their grown up children as a kids is effectively a moron.
It invalidates the child's acomplishments in life to a degree, creates embarrasement and is just being plain disrespectful to the child in question.
Everyone keeps saying how children are supposed to respect their parents ... but what happens when parents don't extend the same courtesy to the children?
Where's the two way street here, or am I missing something and society has this ridiculous perception that parents are the only ones entitled to this?
The best bet for the OP would likely be to get his own place which would completely separate him from his folks, or pay for the rent entirely on his own.
The thing is though that arguments would still ensue if the parents would keep coming back for visits and whatnot due to medical reasons ... so by moving to your own place and leaving their old place empty would be the best option in this instance.
If they want to sell the place and want to stay with you, politely decline due to the reasons they are creating huge personal pressure on you while they are there and are adding an even larger disruption to your life.
Tell them you love them, but that this living arrangement is not working for you and is impacting you in a negative psychological manner.
