Hey, doing laundry is good.
I think you are doing the right thing by going back on the meds for depression. It won't solve all your problems, but it can make you feel pretty good about getting up every day. As you probably know, it can a couple of weeks to kick in. I know how awful it feels to think that everything is pointless. But you are a survivor. Beating cancer proved that and you can beat this.
Again, I am very sorry about your brother. It must be so hard for you. But, right now, you do need to concentrate on yourself and getting better. What I've learned from this board is that recovery is ongoing and you need to focus on 'today'.
Did you look on the Narcotics Anonymous board here? The item: FYI: How it Works (by Pernell Johnson) might be of some help to you.
Take care.
Love, Anna
