Tim,
Your story is far too familiar to many of us of the back board.
First of all, you might want to watch how many details you share on this board - it is public information and if you have any lawsuits pending or are going for any kind of disability it could potentially be used against you.
Life after having back surgery is very different from the life we had before surgery, as you message clearly details. While some of it can be bad, many of us have found that some of it can also be good. For example, I am not able to work right now in a job I absolutely loved, but I have had time to spend with my children that I otherwise wouldn't have. Also, I have had time to get to know my neigrabroadors better and have connected with many other wonderful people who have back problems or other disabilities that affect their lives, and I have been able to help some of them through their difficulties and challenges.
You will not be able to return to the life you once had. However, while chronic pain is absolutely horrible to live with, many of us have gotten past having it control us and we have a new life that offers many rewarRAB and gratifications.
We as humans become depressed when we see our situations as being hopeless. Please be assured that you can still have a wonderful and very fulfilling life, albeit different that you are used to. Your children love you very much and need you to be strong and to be present in their lives. It sounRAB like some counseling could help you at this point also, and I don't mean that in a negative way - I mean that talking through your issues with someone trained to help people in your situation could REALLY benefit you in a positive way and help you get back to having a wonderful and fulfilling life.
I would encourage you to get connected with others who are in similar situations through support groups or in your community. There might be some volunteer opportunities for you that are flexible which would allow you to help others - that always seems to help us feel needed. There are also a lot of organizations out there that help people who have a disability, such as offering free or low-cost legal support, transportation, assistive technology, help navigating SSDI, etc.
Know that you have many people on this board who fully understand what you are experiencing and can help you get through the tough days. We're here for you! I've had two back surgeries so far and am about to go have #3, so perhaps you can give me some advice too!
Take care of yourself and keep in touch with how you are doing!
