Mental well being and families

I've been mentally unwell for some time now. But I am making progress. I've had a lot of great support, from friends and professional acquaintances. I've been polite courteous, helpful and hard working. In return I've had kindness and generosity which had boosted my ego and made my recovery easier. In the words of my solicitor though, I'm protected by the disability discrimination act, or the equality act because of my mental impairment. Something my previous employer ought to have been aware of due to my previous stress related absence.
Despite my illness my blood family has struggled to offer any level of meaningful support. Although some have believed that they are being, by offering me visitation's once every couple of months. Other family members have drawn themselves further away from my problems, overwhelming me with their silence.
On occasions, my patience and tolerance has been tested by my families in ways no one else does. I've had the phone hung up on me, I've had family members raise their voices, I've had ultimatums tossed around, and when pushed I've said things I meant.
Yet standing up for my beliefs, protecting my immediate family, my wife and my two girls, has driven my blood family to become even worse. I've defended my position vehemently, and would likely behave the same way any man would under the same circumstances again, but the level of tolerance I've been subjected to has lead to me (and my wife!) questioning our own self worth. Despicable things have been said, not only about me, but bewilderingly about her. When she's helped me selflessly for so long, when they haven't.
It's terminated in the realisation that in order to rebuild any bridges that they've burned, we're going to need mediation therapy. Something earlier this week I suggested. Something that was met with even more hate, judgement and vitriol, that it's exhausted me.
Which leads me to my conclusion.
Family are no different to anyone else.
They either have a positive affect on your life, (I believe they should. Especially when some family members need it more than others). People either judge or love unconditionally, or they hate.
People either lift you up, or they drag you down.
Whether they're family or not. If they're part of the reason why you're suffering. You need to let them go.
And if they see you as such a negative influence on their lives, then it's probably best for everyone to break off contact.
