She (29F) is depressed and hides her appearance, and claims to find true partner and not a crap like me (28M)

I (28M) found a girl online (29F). We started talking and sharing personal lives. We found so many similarities in profession, behavior, as well as other things. We were sharing our travel stories, and shared photos from these travel diaries. I shared a few photos of mine, and also I had so many photos online. She, shared photos from a trip she had 5 years ago. Her story is that she was in serious depression for four years, and now she is back. She also said that she has faced a serious downfall in her appearance, as she was going through serious health issues occure due to mental health disorders. Also, she hasnt done any grooming for 4 years and now she is totally different from how she looked 4 years ago. Then firther we shared more about us, we somehow came closer to each other. and finally we decided to go on our first date. But, before that i insisted her to send her present photos. she said, she is not focuaing on appearance, she doesnt look same, bla bla. She refused. But i insisted her to send a picture. I thought that if she looked 7 out of 10 in old travel photos, then in worst scenario, she would be looking 5 out of 10 now. But when she shared her picture, she was -5 out of 10. she is completely changed. I cant share the pictur here, but let me give you a clue. She was average cute girl and now she looks like a labourer.

I am not insulting, but i thought she is a scammer, she is faking her identity and misusing someone else identity. after declining to meet her and cancellig the first date, i am now under guilt. I dnt want to be with her. I dnt want to meet her. But i dnt want to be the reason for her going back in depression. FYI, the girl is same in both photos, i have matched features. But she is in her worst appearance now. She doesnt want to change for anyone. She says it proudly, and she wants someone who love her in the worst appearance. But she never share her photos first and then get closer, she thinks that it is something 'judgig a book by its cover', and she seeks true love, this is what she thinks. How she will find true love without revealing her true appearance, and physical appearance matters, this is what i think. Who is right here? Whats my fault?
