Struggling with Depression and Loss of Therapist

my depression is the worst it's ever been. it doesn't help that my therapist left. any advances I made, I've slid backwards. not making my bed, not cooking, popcorn is my dinner tonight, not wanting to bath, not watching TV, not leaving the house, unless I absolutely have to. I actually did start on my book hoard. I took 7 boxes to the thrift store. have lots more to do. so, that's a good thing...my neighbor knows my issues and keeps trying to get me to go out with her to dinner or to see a band...she's not offended when I say no. she is in worse physical condition than me, and uses any opportunity to go out while she can...I guess she doesn't have any depression.. ..I read all the time...that's my escape..
