Do you ever randomly get down?

Like depression but it only lasts a couple hours?

Randomly for a couple hours a few times a week or less I just feel like theres no point to anything or just "eh". I dont feel excitement or anything but agitation.

Then a couple hours later Im like...totally fine and kind of shocked I felt that way.

Possibly a trigger**

Its nothing over the top. Im not talking suicidal thoughts or anything.. just a down mood that makes me feel im depressed.

Does this happen to you? Is there a name for this??
