I'm super confident and have little trouble picking up females but once I kinda have them liking me I'm no longer happy, they no longer give me the external validation I require! Compound this with Mild ADD and it ruins every attempt at a relationship I have! Is their anyway I can satisfy my relentless need for external validation or does it stem from much deeper issues? I'm not really sure any of you will be able to offer guidance but hey worth a shot
