Im sorry she came at you like that. She sounds like she might be a person who might need to stick her foot in her mouth often. I know and am very close to a person like that. She never really means to put me down she is actually trying to compliment me but it always comes out in a condescending way. I actually avoid conversations with her in certain moods because I dont want to be offended by things she says because I know she doesnt actually mean to be mean to me. I think this woman was trying to tell you that you are doing better. Im sure she realizes you had improved already before and are still improving. Your work is definately not worthless. Working on you and better yourself and your life could never be worthless or pointless even if some people dont realize the hard work your doing there are those that do and you can feel better about yourself too. But yet I do understand the sting your talking about, I have felt it too. Just let it roll of your shoulder because people just cant understand exactly how hard we work at trying to live a normal life because they have never had to try it comes naturally for them so they assume it should for us too..... so not the case. Hugs to you
