So today is unseasonably cool and I felt like I had much more energy!

After work and cooking dinner I had energy to plant four potted plants. It took about 30 minutes. After I was done and would stand straight my leg muscles began shaking. Feeling like I would not be able to hold myself up. An our later I am laying in bed and they are so sore and weak. I did not over exert myself!
I feel weak and fatigued so much that I love an opportunity to do something I really enjoy, but I end up suffering for it.
