g,
Enjoy the "stress" of "getting ready" for a new life.

If you can, try to let go of the hurt/anger towards those that did not support you when you needed it most.

I don't have much [to offer] when it comes to dealing with insane medico/legal systems, but that is also a reason to pull yourself out of that main "hornet's nest", so that you can see things with clearer eyes.

These kinds of dysfunctional relationships can occur in any "family", and when things take a turn for the worse, they cannot be counted on. It is nothing personal, sometimes, some people are just not capable of "support" or unconditional love, even when they are the people we think should be the ones to offer it (the people that gave us life).

It sounds like the "family" you are heading towards is the one to cling to. Walk away (from the old one) and don't look back.

Reward your love and kind heart to someone (your soon to be DH) who clearly will return that love in kind.

Walk away, don't turn back, and embrace what you are heading towards.
