I'm onboard with everything that @coffee said except for one thing:
The Stoic schoools focus on true individuality, being 100% in charge of how you think, act and feel.
Specifically, I don't think as true individuals we are in charge of how we feel. It is something that we can influence by thinking or acting on it, but fundamentally it is a state that comes over us and of which we also have no control. It could be caused by a hormonal imbalance, fatigue or stress. So it is important to acknowledge it for what it is and to think and act to resolve it.
