I used to feel bad about wanting alone-time. It seemed selfish when others wanted to spend time with me but I wanted to be by myself.
The reality is I function better when I have plenty of uninterrupted time alone. It gives me time to think, process things, and replenish my energy. I don’t have to filter anything that I’m saying or doing, so it’s not tiring. I’m unrestricted. I can never be completely unrestricted around others, so it will always be a bit more work than being alone.
