I am sorry this happened to you.
I also know how hard it is to be a friend to someone in severe MH crisis - I grew up with a parent who was very emotionally unstable and attempted suicide a number of times.
And I did end up estranged from him, because nothing I did could ever be good enough, and I couldn’t keep on pouring all of myself into supporting him when all he could perceive was abandonment and betrayal.
The more we all gave, the more he needed, and none of it was ever enough, and he would lash out and make us all feel guilty and threaten to kill himself. It was part and parcel of his mental illness.
I loved him very much. But his insistence that none of us loved him drove us all away in the end.
I often think how hard it must have been for him to feel so unloved - when we were bending over backwards to love him, despite how aggressive and hurtful he often was. But he couldn’t feel our love at all, and genuinely believed everyone was out to get him.
So now when I meet someone who can’t register the good or neutral intentions of others, I steer clear. Because I am not going to be put in that position again of giving my all only to be accused of betrayal or abandonment.
I really wish for you that you can be open to the possibility that you are cared about. And I hope that you have the support you need. 💐
