OP, anyone who says hell doesn't exist only has to read your story. As with other posters, my heart goes out to you. You are in hell at the moment.
However, although I have not been in the same hell as you are now, I have also experienced times of pure hell. One thing that I learned to ease the unbelievable pain was to let go and go with the hell, to stop trying to fight it, accept it. I tell myself that people have been through hellish things since time immemorial, it is not something new or especially tailored for me.
You sound as though you are currently experiencing quite a high level of addiction ie to your husband and to alcohol. Addictions are devices to facilitate turning away from unmanageable pain and are, sadly, not the answer: they not only don't help, only in the very short term, but actually makes things a lot worse, compounding already unbearable pain.
I hope by now your ADs have begun to work and you are beginning to feel calmer. You need a lot of RL support and please access all the support you can, not only for you but your surviving son. I am concerned for your son, who has lost his entire family one way or another and is also battling a serious illness - does he have his own support, separate to the support you are receiving?
Please get back to your supportive GP and request support from your MH crisis team to support you through the intense crisis you and your son are experiencing at the moment. There are times we are so ill we have to give in and allow others to take over and look after us.
I wonder if you have had a payout from the court case you won, or are you still waiting for the legal machine to facilitate that? If you have any spare cash, please consider paying for intense, possibly residential, care to get you through this truly dreadful time. If you don't have any 'spare' cash, can you free up some? YOu are understandably not at all well and need conclusive support, can't be dependent on people's goodwill (or neglect
) and need a haven to recover from the shattering events of the past 5 years.
I assure that taking your life will destroy your surviving son, please don't think otherwise - it is a lifelong burden that is agony to bear for those left behind.
I wish you well OP
