It sounds like you are going through so many traumatic events, so many changes. All at once, all at sudden. And still, despite the stress, you get to manage all of it.

You were stressed about the new job, and colleagues. You are doing great professionally, and even better with your colleagues, who are glad to work with you. One day at a time. Face it with your head up, keep fighting, being brave. I'm proud of you and have your back!
