Have just come across your posting. Unfortuntely I cannot pass on any advise to you as I am in my 10th year of struggling with my son. The fact that I love him, and I know that he loves me does help - allthough I have to say that sometimes I think he doesn't like me and I don't much like him - but I know that that is all because of his symptoms and so I plod on.
Be pleased and take full note of every little achievement, every little thing that goes right - it helps to get you through those times when you don't know how you are going to cope.
I know that that sounds trite, and its not easy - but do try.
Also post on here. In the past 2 weeks that I have been posting I find it has made a difference to be able to post when things have gone wrong, and on the two times that I had a little 'win' it was good to be able to post that as well.
Good luck, hang in there.
