OP: You are in a tough situation. Thankfully, you are not alone. Good thing that you are able to look for ways to make your situation better.
It sounds like you are going the London route not the Copenhagen route. In case this is not settled, or in case it is helpful for another reader, I just wanted to raise that Copenhagen is very dark in the winter time. You mentioned issues with light at your LAC, so just wanted to be sure that was on your radar. (The summers on the other hand are light-filled.)
