How appropriate that we are having a squirrel conversation in the "tree house".
Welcome to Neuro Talk dear reyn. (my "job" is to welcome new members even when they are old friends.)
Depression is hardly an old friend...however it is a very familiar one. How I wish Pter were here to help in the fight. I am so sorry to hear that you have barricaded yourself in your home when the antidote to depression is to surround yourself with people who care.
There are a lot of people here who sincerely care so let us help you up.
