6 1/2" tree sounds like too much to deal with. I have the same and it was a lot of work getting everything put away.
Do you decorate for Spring ? Maybe just some fresh flowers. ? I did manage to go out but felt awful that I've gained so much weight that I didn't buy any clothes. I bought my dog a sweater since its going to be -34 degrees on Saturday.
I know you'll feel better. Maybe once winter is over,all of us will feel better. The gray weather doesn't help, does it?
