Hi, you also have my sympathy regarding this. It totally envelopes you in a cloak of misery doesnt it ? You sound like you are doing all the right things in my opinion. And dont fret about the feeling better when she is not there , the very same thought has passed through my mind.
I also have questioned what I have done, and you know what we have done nothing. The age they are at dictates they are selfish little madams. My daughter who is finally home was asked to wash up today, she announced that she is working tonight. DH said that as parents we are always working and doing other chores, what was she doing to contribute....nothing at all. She didnt reply, probably gave a dirty look.
We also wonder how long the school thing will last. We kept her side last year with a teacher who was ready to throw her off the course,this year she is on her own. She now says she has a focus, but is showing no inclination towards study, though her attendance so far is ok. She is now admitting of sorts to be going out with the weed smoking loser, (not letting her know my feelings anymore) and spending more and more time with him.
The hardest part is letting them learn the hard way isnt it, but my daughter clearly wants to and as a parent I now have to let this happen.
I have decided to back off totally, let her stay over with him and let it run its course. Its a nightmare, but am hoping it will fizzle out, plus all the advice I have been given here has been no end of help.
Dont blame yourself for this. Read the excellent advice that people have posted to me on this thread and detach ........ and take some comfort that you have support here to see you through. I really hope this helps. It wont make her come home, but may help you get your head around it all. Stay strong. I am confident our DD will one day be proper human beings !!!!!
