We will quit jobs, friends, hobbies and etc while operating under emotions. We will think the world is against us. We will see things in our favor only.
When you operate by your emotions you will do things you will more than likely regret later especially if you are upset/angry. Recently, I made this same mistake and God put a guilt on me that only could be repaired by going to the person and apologizing. I mean I went off you hear me. I called others got them involved it was bad. But it was something that was brewing for sometime. One day I snapped I didn't see things rational.I didn't go to the person and try to talk things through. I leaned on my own understanding. I ignored the voice of God telling me everything was going to be okay and don't give in. I did it anyway. When I came down I was able to see things clearly, what led up to this. And I had to apologize. I felt so bad I never felt this bad in all my life. But it was my fault I heard God's voice his direction and did the opposite.
Advice: wait to make decisions after your emotions subside. Make sure you don't have yes people around you or people that will further allow you to give into that emotion. While emotional be careful who you confide in. They may also be a component and make things worse. Especially, if they weren't there and you are telling them the story.
