Some friendships have taught me that you can’t build walls around yourself and then expect others to figure out what you’re going through. Communication is the keyword. If you can’t find it in your heart to be honest with your friends then you have a lot of things to figure out.
Your real friends often care but they can’t always break extremely thick walls to get to you. Blaming others for not being able to reach out while you’re the one who ghosted them is childish. At the end of the day, life is too short and everything is temporary even your feelings. I hope one day when you look back you won’t have any regrets for letting go so fast.
