anxious and discouraged

I haven't posted in a while, so there are a lot of new voices. I am a 50 something wife, mother, and grandma. I am a caregiver to my elderly parents.
My youngest child is a transgender woman. I love her and I am proud of her. She is working on her doctorate in mechanical engineering. However, I feel as if Im failing her. I communicate with her pretty frequently, but it feels as if I am the only family member even trying. My older children 32 and 25 seem to be avoiding her and I know she's aware of it. Its breaking my heart.
I also am in the process of leaving a job I have enjoyed for almost 5 years. I am basically looking forward to the opportunity, but leaving my students and the staff I've worked with is tough!
I am struggling with the knowledge that I am failing in so many areas.

Hello guiltier: I'm sorry you feel you are failing in so many areas. It sounds like you have an awfully lot on your plate. From what you wrote, it doesn't sound to me as though you're failing. You certainly can't be responsible for how your older children are treating your transgender daughter. But I know how it is. One still feels there ought to be something one can do... even though there probably isn't. Your older children may well come around. These things can take time. As has often been said... it's their transition too.

Anyway... it's nice to see you back. My best wishes to you...
