Just because you can't work doesn't mean there aren't things you can do.

Spending too much time in bed is especially difficult on the spine and you already have numerous pain complaints. While I know MS can cause chronic pain I really wonder if there isn't more going on with you than just MS.
Like others mentioned the amounts of medications you self-administer is alarming. Sadly "100 people die from drug overdoses every day in the United States"
Please be careful.
