Okay, this reply might seem a little different...as it is a conglomerate of Fran's, Suz's and Stars. Sort of a moderate approach. I am factoring in your intentions.
We've been in this spot countless times. If there is any tendency toward confusion, this kind of thing would be it. If it is in your own best interest to help out your difficult child, should you? We have a few variations on a theme. One is to see if she can meet us half way. That is, require her to do her part toward a situation and we (assuming it was in OUR best interest), would do the rest. Like in this case, have HER update her own resume, but you make some phone calls. Share in the responsibilities. Additionally, how bad was that "pulling teeth" business? Was she disrespectful to the point of causing family anguish? If so, you might have handed her a list of the jobs that you found and told her you would like her to call them. THen walk away. Disrespect cuts off mom time in my book. AT the same time remind her that you will put her on a budget that will be mighty limited and if she doesn't have a job, she won't be able to keep up with the others in terms of little extras, etc. Then, stick to your guns if and when she doesn't have a job and runs out of money. You can only do so much. Too bad, so sad. Hopefully, she will take the ball and run with it. If not, you can not cram the ball down her throat.
Normally, I would have HER do all the work, but if she is stuck and it would be in OUR (your) best interest, I might be willing to help out. However, if our daughter is not willing to do the least little thing, or is disrespectful, then we know not to bother.
I do wonder if she (your daughter) might be worried about working and going to school at the same time. Perhaps she is worried about how she will manage it all. It is alot of responsibility. However, other students do this and when you are young, usually extra energy is available...esp. if you are motivated. I like the idea of doing your best to get her to the college, in the hopes that she will like what she sees and work hard to keep it. However, I wouldn't necessarily go overboard....I would not hand things to her on a silver platter. This just never works with young people, and this goes double for difficult children.
What we have found is something curious. When we have tried to do the meet me half way thing with- difficult child (cause it is in OUR best interest) and she doesn't want to do her part or is disrespectful and then we say "so be it difficult child, then you don't get our help at all and you are on your own..." difficult child will grump and double check with her friends about it all. Guess what? They come down hard on her and call her a "dope." LOL! Lately, if difficult child is "stuck," and we make this type of deal, she is quick to grab it and do so with gratitude.
You might want to have a discussion with your daughter about budgeting her money in college and about any fears and/or concerns she might have. Additionally, see if there is a counseling center available and encourage her to use it should she feel overly stressed.
I don't envy your dilemma here...
Hang in there...wishing you well.
