I, too, remember you and your concern for your sister. It is so good to hear from you again. I am glad to hear the KC is doing better. I do hope that she finds the motivation to get back to work and/or school. Since she does not talk to you, there is very little that you can do. So, try not to stress yourself too much.
I am glad that your family is adjusting to the "new normal"..it does take time and the best part is the fact that they are trying.
I agree, once you relieve yourself of some of the issues that cause you stress, you will improve in your schoolwork. Do what you can to alleviate those issues.
Until then..welcome back
Peace and Blessings
Look For The Good and Praise It!
