Welcome to the forum Kateline1, we're glad you're here.
When you stop and think about it...things are backward when we allow our children to have this kind of unhealthy control over us. Walking on eggshells is a sign of an unhealthy relationship, as I am sure you know.
Some things to think about:
1. Give her some space and time. Stand way back for a while. Just go silent.
2. If you decide to reach out to her, say very little. Keep it short, cordial and simple. That will likely surprise her.
3. Turn your energy on yourself. Start by doing small kind things for yourself. You deserve good things and a good life.
4. Seek out people who respect you and care about you. Start spending more time with them.
5. Get plenty of rest, eat well and do some simple things that you enjoy every day, like taking a walk, reading a book, taking a nap.
6. Many times, these types of situations don't stay the same. Don't start thinking this is forever. Just wait and see and give it all some space and time. You might be surprised.
We can't control other people and how they behave. The only person we can control is ourselves. I know her behavior hurts you, and of course it does, but walking on eggshells isn't going to change that. Let her know you respect yourself too much to stay around that type of behavior.
You might be surprised in time. Hang in there. We're here for you.
