Highs and Lows

This morning was the first morning in 12 days that I haven't felt extreme exhaustion and needed a sleep mid morning. Things were looking and feeling good, I had energy. I tidied a bit, put dishes away and secured a new mortgage deal over the phone.
I felt like I was better.

Then it went wrong, and I don't know why . All of a sudden I felt numb, emotional and tired.
I sat in Starbank Park for a bit watching the sea and in tears. I think I also fell asleep for a short while.

I can't do this much longer. I hate me just now.
