Control Your Mind and Master Your Feelings

you learn from past mistakes and alter your perception of what will happen in the future.

The best thing to do to take care of this is to accept that what is done is done and the future is untold, so all that matters is what you can do right now. What you do in the present can help

Cortisol is a stress hormone and when released into your body drives symptoms of sweating, shaking, feelings of fear, nausea, and other alarming sensations. When you overthink, you are actually causing unnecessary stress to your system which then stimulates the hypothalamus to produce excess amounts of cortisol. This is why you have anxiety attacks or become triggered out of what seems to be nowhere. The amygdala and the hippocampus work together to process the experiences you go through into memories. These memories can lead to triggers later on when you undergo what you have trained your brain to feel as fearful or dangerous. Have you ever just sat there, having fun with your friends, and out of the blue you experience a panic attack? That is because the conversation, or the environment, or even an odor has triggered the hippocampus to send danger signals to the amygdala, which then activates the hypothalamus to send hormones throughout the body to prepare for the perceived danger. This only happens when the limbic system is damaged. The cure to this is to stop overthinking. But how? The next few steps are some broad general guidelines to retrain your brain out of overthinking:

This is what the hippocampus does.

to chronic stress caused by overthinking everything - you may find it difficult to remember things such as dates, events, names, and putting memories into chronological order. Damage to the left hippocampus affects how you recall verbal information. Damage to the right hippocampus affects the ability to recall visual information. Damage to the hippocampus means that this part of the brain can actually shrink in size. If it shrinks you have a higher risk of developing Alzheimer’s disease and significant decreases in memory performance.

This is what the hippocampus does.
Brain scientists have found that there is a rear part of the hippocampus that implements different types of memory. The rear part of the hippocampus processes spatial memories. Spatial memory processing is when someone memorizes the route to different places in a big city or memorizes complex things turning it into photographic memory. Sleep regroups these memories and grows the rear part of the hippocampus which leads to better memory. It is believed that the hippocampus registers and temporarily stores these spatial and short-term memories then ships them to the long-term memory center of the brain.

Overthinking is undeniably one of the biggest causes of mental health illnesses.

The same neurons used for planning and problem-solving skills are the same neurons used for when we worry.

Remember that knowing your opponent before a battle is essential to ensure that you emerge victoriously.

The problem here is that you are not fixing your core issue - overthinking - you are making it worse.
