Just because something ends doesn't mean it never should have been. Remember, you lived, you learned, you grew, and you moved on. Meaning. Some things or situations in your life will have to end, but that doesn't mean those things aren't good. No matter how it ended, you've learned from it, lived it, grew, and moved on to another good thing.
Life is full of ups and down. The way you handle it is all that matters. Family fights and relationships end, but that's not the end of the world. Ends are not bad; It's just a way of telling you that you have to move on to important things. People tend to believe that things will always go smoothly, but then, some things have to come to an end. It doesn't have anything to do with you: That's how life is. It prepares you for different situations; you need to grow and move on from the previous one. But the most critical thing is to have learned from it, grown, and then moved on. So please don't dwell on it; better things are coming to you.
Next time you are in this situation, remember this quote and use it to overcome your challenges. Even though it might be one of the difficult things to accept, know that something better is coming.
