Wow, the pain that you must be going through is unimaginable. I am tearing up just reading through your and Alex's stories.
It's always interesting to bump into a post that I wrote over a year ago, I usually cringe (I wrote that?!) and wonder what was with me back then. My life is mostly the same, still ups and downs, still going to therapy and still not what I was back then but okay with who I am now.
Although my story is nothing like yours therapy really helped me. I think the most important thing right now is to find yourself a place in your spirituality that you are comfortable with. Rabbi Twerski writes all the time and I think it is relevant here that spirituality can be defined by anything that is uniquely human. Kindness, self control, love, being there for others, working on growth, and doing what you are doing; working on being able to live a healthy and stable life are all things that only humans can do. You may think that the only "spiritual" things you do are kosher and washing your hands in the morning but in reality, every time you choose to live a happier and healthier life you are doing something spiritual. Making choices is spiritual and choosing to break the cycle and take your life back is something to be very proud of. Don't be ashamed, not around here.
If there is one thing in my previous post that I would write again it's that this is a slow and gradual process and skipping steps is like overwatering a plant and drowning it.
AlexEliezer is one of the most inspirational guys on this whole site so I would take his outstretched hand and see if you two can connect. His posts are super powerful and I am sure that reaching out to him will really help share the burden.
Keep it up and please please please update us more often.
All the best,
