((Hugs)) Miss B., so sorry you are down right now. I have had problems with the black dog (depression) myself. I hope it hasn't been going on too long, if so you need to get help. It's understandable that you would feel down, it's rough losing family, but there are ways to deal with these things and move on with your life. Time is a great healer, so keep that in mind.
What helps me is being creative, exercise, volunteering, journaling and meditation.
I have a small business fixing up old furniture and selling antiques. I don't make a lot of money, but if I don't have a creative outlet I don't feel right. Do you have a hobby or interest you would like to explore? Have you thought about volunteering? Helping others is a great way to feel better, plus you meet nice people.
I highly recommend meditation. It's good for anxiety and depression, plus a lot of other things. I went from blood pressure of 140 (high normal) to 115, it also helps with my ADHD. Here's a website that has a quick how to:

Journaling also helps with depression. You just sit down and write what ever is in your head, a few pages every day. I don't know how it works, but it does.
I hope that helps a little. PM me if you want, and please let us know how you are doing. We care.
