These feelings come in waves, and sometimes they come too large. I'm learning that in my life, there is no such thing as a forever. So savor the greatness. Savor the little things in life that allow you to enjoy it, even if they are minuscule. Savor love, in all of its forms, wholesome or not.
Know that even though a storm could show up at any moment a clear sky will always follow. Maybe knowing this, feeling guilty will be a little less of a feeling. Maybe one that isn't a feeling at all.
