I can relate.

I usually have more trouble with this later in the day--I have noticed I stay more positive when I get enough sleep. I won't completely give up my coffee but I have switched to decaf after having my first two cups every day. This is helping. When I have a negative day I frequently go to bed earlier because usually the negative mood is gone in the morning. Did you sleep well last night?

Did you notice a trigger? What did you think or what did someone say right before the negative thoughts started today?

This morning my husband made a comment that was triggering for me. I considered ignoring it, then carefully told him I that I was hesitant to react to the message because of how the conversation went last time. He ended up saying he understood my confusion, we discussed it. His comments about this subject no longer seem like a minefield for me. A lot of our problems are communication problems--I jump to a lot of conclusions in my head because I assume he is upset about something I have done.

Mostly, I enjoy the people I work with but there can be people I don't enjoy. In a work situation, it doesn't always pay to discuss issues we find negative. It depends on whether or not the situation is likely to come up again and other factors. Sometimes there are negative people at work who can't be fixed.

Another tactic I use is try to control what I can in my life for the good--like the things I eat, how I spend my money, exercise and generally take care of myself. When I do what I know is the best for me in the long run--it gives me a positive feeling.

I hope your day turns around!!
