I feel your pain my friend. I know exactly how your feeling. Just a couple years ago I would be lucky to be able to sweep the floor on any given day, being overwhelmed over just having to breathe and get through each day. I remember one day I mentioned to my grandma that I was depressed (and I was crippling depressed), but she just said, "depressed? you have nothing to be depressed about." Well I know depression can look like some phase we can soon snap out of in the eyes of others who haven't experienced it, but we know what it's like, and you are not in this alone.
My husband doesn't understand either (which is understandable) why I struggle with simple everyday tasks, but it's not the end of the tunnel, as long as there's hope and we are doing whatever we can to reach the light. I am here if you need to talk.
