Depressed

I have been experiencing more days of depressed mood over the past 3 weeks, than beofre that time. I am hoping to find encouragement. I have been isolating more than usual, which is something I do most of the time. Usually I do not care to be around others, except for two close friends. But lately, one friend has been ill and I have not been able to reach her. The other friend was out of town for several weeks. 
I think it would help to do just a little volunteering, maybe with animals. I just don't think thst I am able right now to make a time comittmment.
I have small dogs. They youngest is very affectionate which I love. Volunteering would get me out of the house though.
My hygiene has not been the greatest. I want to shower but do not have the energy. Also have physical problems, hypothyroid, extremely low iron, red blood cell count, etc. I'm sure these are contributing factors.
All I really know for sure is that I have been feeling very, very sad and once I start crying, I use tapping, deep breathing, get some relief, then the flood starts again. Also take my meds and use distraction. Sometimes that helps.
My daughter and grandkids do not seem to care abt me. When they are here, they are all texting. Guess I'm just not exciting enough for them, but it hurts like hell.
