in general ppl tend to lack self-awareness and emotional intelligence so they think their emotions are at odd with their rationality. but our emotions tell us things that stoic reason cannot. emotions in general are not irrational, the feelings we have are, at their core, expressions of need.
sometimes we feel desperately sad when we’re alone. we might think of calling someone from our past who used to give us comfort. logic may indicate that this is not a good idea, but this impulse is a signal that your needs are not being met. loneliness is a rational response to your need for companionship being neglected.
the emotion driving you to drunk dial an ex, or something to that effect, is not some wild unreasonable thing. it’s the first step in the process of making a decision. you can follow the emotional wave and send a risky text or you can talk yourself out of it because you feel like the outcome is predictable and unfavorable. both are rational. both are logical. duh
Gary Zukav said that emotions are like pain – they’re calling our attention to a need, not just afflicting us needlessly based on outside stimuli. if you break your leg, the pain is alerting you to the break so that you can take action. when you have negative emotions, they’re alerting you to something that you need to be happy and whole so that you can take action.
