Mera, Sorry you are going through this.
I want to commend you for keeping it all together and coming up with solutions to your challenges. For example, the cargo bike is a great idea!
That being said, one trick might be to plan your day on the previous day. Try to write out a detailed 'todo' list of things to accomplish for the next day. When I do this, I just get up and try to go on autopilot, so to speak, and begin doing the things on my todo list. The accomplishments help settle me a bit.
Also, I try 'grounding techniques'. I read about them in my PTSD book.
Best to you,
Stella
