Hi Nann, there have been many times that I have felt the same way. I think that most people do not understand anxiety or emotional issues, so they can't empathize, and they just don't know what to do or say to help. My mother in law is a perfect example; when my Mom passed away in 2012, I was utterly devastated, and falling deep and fast back into the worst anxiety/depression. All I wanted was for someone to be with me, to console me/show some empathy. My Mother in law only lives a few blocks away from us, but never showed up. At the funeral she did not even hug me, or offer any kind words at all. In my mind I thought she should have been more helpful toward me. But, I know the woman well, there is only so much she can give, as she is one of those people who thinks anything and everything is about her, so she doesn't feel sympathy very well, I would say she is kind of a selfish person.
On the other hand, I have known a handful of people who understand, and offer help when it's needed. The people I speak of understand because they have experienced the same kind of pain, and therefore they can genuinely empathize.
I find that when it's hard to find someone to care the second best option is to be there for yourself. Nurture yourself with good food, relaxation time, exercise, good books, nature, anything that helps bring you back to center. Even though it's always nice when someone else cares, we do have the capacity to be our own support system by doing those things that naturally calm us back down.
Best of Luck! :)
