The Spoon Theory is an amazing way to explain the energy drain that many Autistic people feel. If I get too low in Spoons I get VERY sick so it is important for me to conserve my energy and avoid too many activities that take away the most spoons.
Some activities take more out of me than others, even enjoyable activities can be taxing on my spoon supply. Socializing and having a full time job uses almost all of my spoons most days. Sitting under florescent lights or being in a loud noisy environment slowly drains my spoons as well.
I limit my social activities and don’t get out on days that I go to work since these take up so much energy.
Also I need time to “regather my spoons”. After I get worn down it takes time to build my energy levels back up. It is extremely important that I have quiet time to recover or I can get stuck in a repeated meltdown / burnout loop.
