There is no such thing as an excuse. You either did it or you didn't, you had it or you hadn't, you gave it or you kept it.
Take responsibility for your actions, make things better if you are not happy. Do everything 100% to your abilities, trust in others to support you but don't expect them to do things for you. Ask for help when you need it, don't wait for it to fall into your lap.
A lot of thing are not easy to figure out, but listen to your gut feeling. Your body tells you a lot of things if you only listen. get in touch with yourself, and a lot of things will fall into place.
