There's no mistake...
There’s no mistake what happens in your environment/life. You are where you are for a reason. Figure out that reason so that you can be able to move forward. You don’t come across people just because. If someone did something to you abruptly rude, you may want to figure out the energy you are attracting.
Nothing is ever a mistake. There is no coincidence. Keep putting out positive energy so that you can receive the same energy in return. Stop blaming others and critiquing others when you have the same amount crap they have. Remember every situation good or bad is to build your character and strength. Always keep in mind when you point a finger, there are three pointing back at you.
Pray on your life and surroundings, it will get you through life navigating you to point A to point B. There's no mistake in your life, although it may seem that way to you. Everything literally happens for a reason, you just don't know it yet. You just have to be mindful and always look within when everything external does not seem right. And thank God for when things are going right in your life.
