Sounds like based on your past you may be holding on to something and as a result it has now slipped into your adult life. You have the right to feel overwhelmed but its how you look at it that will define you. The fact that your moving forward with your life is a accomplishment in itself. You’ve picked up some pieces to the puzzle, but just like that puzzle box their are either some pieces that are missing or a few pieces to other puzzles that dont belong. It may be helpful to realize that this busy time is only a season. Your working towards a goal. If you have supportive people around you know and friends you may be feeling unworthy due to having non supportive family. You deserve it just like you deserve to be happy. Remember happiness is a choice. You are in a position to accomplish some great things. You’ve picked yourself up, you have love, friends and a bright future.
