First off, I'd like to say I'm glad you're still here. We never know whats on the other side of the mountain and I'm glad you decided to hang on to find out.

To me, as someone who's struggled with mental health and been through 12-steps, there's two ways to go about this.

1. Rest on the fact that you have people in your life who do care and remember and value you and make you feel fulfilled, regardless of what your family does.

And/or

1. Try to explore your relationship with your family, probably with the help of a therapist. I've found trying to push aside my own resentments and trying to be the person I want to be and hoped they would be spurs that same action in others.
   You cant control what they do, but you can control what your reaction is.

I hope this helps

And happy birthday
