think about the Doctor's advise for DBS. I understand the prospect seems like climbing Mount Everest and ultimately this is a decision only you can make, however it may be a good option. Have you explored with the Doctor the benefits you may expect to see as well as the drawbacks ?
Forgive me if I sound condescending, you are going through trials I can only imagine. We have been "virtual friends" for a while now and I wish you nothing but goodwill. Shame I cannot come up with better advise
Take care,
Neil.
