How can I strengthen my ego

The ego is good for one thing, to collect data and information. The problems begin when we assign to it the task of making decisions. The ego is not capable to making decisions!
Therefore, the first step is to relax the ego and reassures it that you don't expect it to make decisions. Only to bring you info, so you can decide then what steps to take.
Let's use an example - a friend tells you that she saw your boyfriend kissing another woman. Your ego brings this info to you through the senses. Normally, at this point its role should have ended. But you might get jealous, upset, angry and immediately decide to call your boyfriend, confront him and end the relationship. A balanced ego would step aside to make room for you to make the decision. This wiser you feels your bf's love, trust him, but mostly feel secured in your identity. Therefore, you don't jump into conclusions, and you wait until you speak with your bf who tells you that he met his sister and kissed her. 😊

For the night times, tell yourself before falling to sleep "I am safe, I am secured". And Repeat this several times with conviction. Your mind will remember this when encountering a scary situation.

I thank you from the bottom of my heart, a hug friend

🙏
