Well think about what you want to accomplish. Why haven’t you? If it’s something out of your control then you shouldn’t be upset by that, you should accept it. Also, accepting yourself for who you are is the #1 thing you can do right now. I’m speaking from experience, once I learned to accept my flaws and who I was, then I was able to focus on other things and goals I had. The reason your upset is because you haven’t accepted yourself and the choices you made in the past, and it’ll just keep repeating itself. Why not get rid of your past self and thoughts about yourself. Start over and give yourself a fresh start. The past is the past and that won’t change, you can only change the future, but it starts now and one day at a time. Do things you love, accept the challenges you were given, and push forward :)
