I am so sorry to rad about your dad. My condolences go out to you and your family. Death tends to bring out the worse in some families. I am so sorry that this is happening. Take the skills you learned and DB them.
Sounds like you have plan, i.e., converting a car into a micro camper and traveling. I think that is a wonderful idea and one that I know you will accomplish.
After what we have experienced, it is not difficult to pick up on who is acting a bit odd. There are quite a few out there.
Please take care of yourself.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
