Keep it in check.

My brain plays tricks on me every now and then. It instills confidence at times of promising news but then comes crashing down once doubt sets in. Doubt that is set off by literally nothing. Or reading into things too much. A non-response. A delayed message. A piece of gossip. A change in plans. That's when I panic. Headache, coupled with more layered thoughts that soon paralyses me from doing virtually anything but worry.
