No matter how hard or uncomfortable it is, you have to sit with them, you have to listen to your voices....And if you have the mental energy to do so, write them down.
Often times, the feelings you dismiss as minor end up having the most impact on your overall health (be it mental or physical)....Your body can feel when you're suppressing your emotions and it unfortunately makes you prone to diseases and disorders (believe me, I am currently being diagnosed for crohn's)...You also become more agitated and exhausted without knowing why....
These repressed feelings can be in the form of burn-outs, intrusive thoughts, anxieties, or any strong emotion you face throughout the day. Regardless, you have to address them...
