oh dear I can really relate to what you're going through and the intensity of the emotions we can have for someone that they won't go away in few months...
but at the same time I think you better help yourself, shake your mind. remember that you are a unique individual. u have inner power and u can be emotionally independent and strong so u won't need your ex-T or anyone else to complete u or make u feel good.
start thinking about all the new amazing things you can do in ur life cause you are great!!!
hope It helps you
