Hi Paul, I certainly don't think that you are weak at all, you have just always tried to please other people and make them happy, this is a trait that shows you are a caring person which is something to be proud of...
Try and change your life from tomorrow, face the world with your head held high, you are worth as much as anyone else. Wipe the slate clean of your disappointments and start a new chapter. Try to realise that everybody worries about what others think of them, treat people kindly and you can't go wrong.....I am sure that you have much to offer , so make the most of it and truly believe in yourself. Wishing you the very best, please be kind to yourself. Xx
