Hello friend, your story is a bit hard, I imagine that it must not be easy, I have not gone through it nor would I like to experience it, but I think it is the best attitude you can assume before the situation, it is good to cry, it is good to vent, it is normal, but as you say the past happened and it is time to move forward, It is time to create a new plan to get things back on track and to recover the same or more of what you had, I think it is all in the attitude with which we assume our problems or failures, as you say there are many people who go through worse things, like someone who perhaps lost a family member (a child, or a couple) because of the coronavirus, I think they are situations a little worse and more difficult to overcome. So excellent attitude, keep going so I know you'll get back on your feet! :) Greetings...
