Well, for what it's worth, I think that you deserve better people than the family you're avoiding, and so do I (avoiding mine). You are way too good for them. Truth is, now's the time to replace them with improved versions of them, when and if better options are found.
I also want you to know that I'm here for you, if you'll have me, on the forum. Feel free to PM me, and I you. Hugs if you want them. :hug:
I can relate to your entire post. I get huge anticipatory stress, have grieved the loss of my family (still do a bit) and worry that my boss wants to fire me, etc. On a daily basis for the last 10 of my career, which is quite successful, I feel that I don't belong, that everyone wants to get rid of me, and that I should leave because I have no future there and nobody wants me.
In fact, recently my boss realized I'm thinking of relocating, and we talked, and he was actually really sad at the thought of losing me. My husband saw him later that morning, didn't know about our conversation, and told me that my boss looked really depressed. I can't be sure that it was just our conversation about my possibly leaving that made him be depressed later on, but I was shocked how far from reality my perception of myself (as worthless) and others of me (as worthless) is.
People that I interact with over time, even, seem to actually like me, which is still coming as a shock, and I'm 37. Part of me knows I'm good, caring, and kind, but other parts think there is either no such thing, or if there is, I can't have it or else why was I abused so badly by both parents.
Like you, I sometimes wonder if I'd qualify as DID if an experienced DID expert saw me when I lost time, or when in flashback my child parts took over control of my thinking and actions. Whatever I DO have, my sister has it, too. I suspect it is either DID, or DDNOS with PTSD.
This used to really upset me and my heart would pound at thinking about it, reading about it, and worrying I have it. Now, I just don't care if I do because I am what I am, and I'm just tired of running.
