Yes you do!

Remember your end point on that discussion, when you are in a good place you can see that you DO matter. Then, when you hit depression again (and as it begins to ease forever I hope) you will be able to use the "decision" against the depressive lies. You can say, "No, I know I DO matter, I won't listen to depression."

You have reached a good place in your life.

(Remember the story, It's a Wonderful Life. Just because it's centered around Christmas time doesn't meant the moral doesn't apply year round!)
