tired

I am a very top level social person. I work a customer service job in a local social service agency. I thrive on helping people. I run very emotionally high happy. Service to others is the one thing that makes me happy. At work I feel appreciated and needed.
Now I'm in week 2 of lockdown with my husband of 26 years who is in constant chronic pain and barely leaves the couch and does not talk, an adult daughter with developmental disabilities who also doesn't want to do anything but sleep, eat, watch screens and make messes she just walks away from, a young adult son who is on his computer constantly playing games with friends and if he has more than 30 minutes for me at dinner it's big. And to top it all off, my oldest son has been accused by neighbors of selling pot at the corner and has called the police on him instead of coming to meet first.
My only light is my last daughter who understands me so well but it's quarantined in her apartment in the city and my oldest son's girlfriend who is with us. But she is still rather new to me so these circumstances are bringing us close in an unusual way. I'm so down and feel so disrespected and unappreciated by so many. I'm still expected to work from home but am struggling greatly. I know God will pull me through but I don't feel worthy. I'm paranoid depressed angry and yet still thankful my problems aren't worse. Which then makes me feel guilty for all my bad feelings. I'm so tired.
