Hello JMM13
I would like to join
I_Am_The_Fire in welcoming you here.
I am so sorry to hear that your daughter keeps changing the way she feels about you, no wonder you are feeling depressed and avoiding friends.
Here is a link about depression which you might find useful, you just need to click below:
DepressionHave you sought professional help for your depression at all?
How wonderful that you are reading Stop Walking on Eggshells, another good book is Loving Someone with Borderline Personality Disorder by Shari Manning.
Hope to hear some more from you x
