Why am I unbearably tired? Why do I struggle to wake up? Why do I find it such a chore to do everyday things like shower and get dressed? Why does exerting energy one day take it's toll on me the next couple of days? Why does this have to be my normal? Why do I try hard to look alive and energetic around family and friends?
Google the Spoon Theory by Christine Miserandino. It does a pretty good job at explaining what it feels like to be me lately.
