I hope I am not interrupting, I just read the original post and haven't read all of the responses yet, but I wanted to reply.
I am a survivor of severe, prolonged, child abuse (chronic, disabling, PTSD with delayed onset), and "off the charts" MDD, as well as having some chronic physical aliments that I struggle with.
I suffered through decades of abuse and trauma and did not begin my healing journey until I was 37 years old. At the time I first entered therapy, I was a practicing alcoholic, with a death wish. I used to drink vats of whiskey, take handfuls of sleeping pills, cut on myself with razor blades and pray to die. I would let anyone and everyone use me and abuse me as they saw fit and was once introduced to a crowd as the man with "no self-esteem'. (and it was true) I totally lacked self-esteem, I did not value myself, my life or others, in the least.
It has been over a decade, I am 51 now and I am a totally new person!!! ..with high self-esteem, respect for others and a genuine gratefulness for my life. I do not abandon myself to the whims of others anymore. I no longer have a problem with drinking, I am no longer a 'cutter' and I love the man I have become in spite of the past. I surround myself with loving and supportive family and friends and am quite happy most of the time.
I have worked through most of the traumas, but still I have a ways to go. Will it ever end? Will I get to a place where I can say I am completely and irreversibly healed? I just don't know the answer to that, but I don't think it's impossible for people like me to heal; to feel and be, whole and well and normal.
I think that the bottom line is that some people do not choose to walk a healing path and they sometimes kill themselves, either quickly and deliberately, or slowly and inadvertently. I may have to 'walk with a limp' and have different challenges than some people may have, but I am not 'out of the game' by any means.
This is the short abbreviated version of my story and how far I have come since beginning to walk a path of healing. I don't know if I have painted a complete picture, but I hope that whatever answer you come up with, you will be encouraged to continue healing and will enjoy a better quality of life as I have.
I guess what I am trying to do here is to encourage you to heal just as much as ya can, to wear your scars with pride, and to have real hope that things will improve no matter how severe the traumas. They certainly have gotten much better for me than I ever could have ever imagined and I wish the same for you!
