Hi Sweetheart, its understandable you felt/feel insecure, but your being too hard on yourself, i think "sittingatwateredge" is right, what does fixed even mean?
Its so easy to interpret something someone said in a totally different way than they meant or intended, i do it all the time, & normally takes me day's to realise its often my mind just running riot...
you have a chance to carry on & see someone else, that can only bring good things, its certainly not wasting anyones time, please dont be hard on yourself, you seem to have come far, there's nothing wrong with making it about you, it's you that's important

.

i hope things become clearer for you
