Sparkplug---------- I will ignore the parts about your attitude that anger me for now, and just address the things I can do without...losing my own cool.
Just wanna let you know that your mom has needed serious psychiatric care and loving family support for a long while.
I suspect the same is true for you, too (having been in need of loving family support for a long time).
While I AM sympathetic to some of the crap you've had to deal with, I have to be honest in acknowledging that our own attitude and approach can do a world of good or do a world of further HARM to our situations and the people around us.
That 'digging' thing you're describing--digging into the skin--it may be an identifiable psychiatric condition but, unfortunately, I can't remember the name of it right now. I'll write you back later after I hear from a friend of mine who might be able to tell me. A doctor told it to her when one of her loved ones was diagnosed with it.
Anyway...if you're not already getting therapy on a regular basis, I would strongly urge you to do so, because something tells me you ARE a considerate, loving person under normal circumstances...but just haven't been dealing with normal circumstances for a long time, for that to have a chance to express itself properly. Sometimes we need recallibration when the natural ratios in our life get out of balance.
I know some of my words sound hard...but I also know you are looking at your own situation and recognizing at least some of the truth in it yourself...and want to HEAL. Acknowledging all the elements of what went on--the good, the bad, the ugly, the indifferent, our part in it, the other's part in it and just pure dumb uncontrollable circumstances--acknowldedging ALL of that is what can lay the best groundwork for rebuilding...healing...on a more solid foundation.
This is what I would wish for you. You deserve to be able to draw from the positives of your situation and move forward in a way that benefits you and your loved ones around you. I really wish you the best in dealing with this emotionally confusing and devastating time.
Anyone would be confused and overrun with conflicting emotions in your shoes, right now. I hope you know that. Please seek help to sort it out...this is not the kind of stuff that 'time' alone can heal. Conscious effort and, very likely, a professional guiding hand is what is needed to help bring the healing you deserve.
Good luck to you on this!!
