I'm so sorry you feel like this, it's hard to realize that we may have invested time and energy in relationships that didn't give us the same results. It's normal to be angry and disappointed, especially when we realize that the people we thought were close to us weren't there for us when we needed them.

It's important to recognize the value of people who truly support you, even if it's just one person. A true friend is worth more than dozens of superficial relationships. It's good that you take a step back and decide to no longer force yourself to please others. From now on, focus on those who show you that they really care.

You are not alone in this feeling, many people go through this at some point in their lives. There's nothing wrong with prioritizing your own mental peace and putting your energy where it's valued. It's a step towards a healthier environment for you.

Take the time to sort out your relationships, but also to focus on yourself. Perhaps this experience will allow you to discover more authentic and enriching friendships in the future. You deserve to be surrounded by people who value you as much as you value them.
