When you don't feel in control of your emotions, it can be overwhelming. Emotions can be either over-controlled or under-controlled.
When emotions are over-controlled, people feel disconnected from their emotions. You may feel numb and unable to express yourself. This can cause problems with interpersonal relationship as it can be hard to connect with other people. Often people with under-controlled emotions will report problems with anger or crying. Trying to suppress emotions results in ignoring warning signals before becoming emotionally overwhelmed. There are a number of reasons this can happen, often it is the body's way to protecting itself after a trauma. Therapy can help reconnect with emotions and learn to listen to bodily signals.
When emotions are under-controlled, people feel like they are completely controlled by their emotions. Under-controlled emotions are overwhelming and interfere with everyday functioning. These under-controlled emotions can cause strain in interpersonal relationship and diminish overall happiness. A therapist will work with you to understand the cause of your emotional dysregulation as well as teaching skills for emotion regulation.
