Welcome to our group, Tabi.
You're not rambling, you are discussing your feelings and that is wonderful.
I understand the "single parent" feeling. My husband has his obsession - 2 meter ham radios - and he sits there for hours on end also and shhhhhhhs my son when he tries to talk to his dad.
You're under alot of stress right now. You need to decide on what is most important at the moment and try to work on solving it. Go down the list, and only focus on one thing at a time - otherwise you will feel more stressed.
This is one time when looking at the whole picture can be very discouraging.
