I read the letters to someone strangely similar to me

Hello, good afternoon, I don't know how to start this, but here it goes: a friend/acquaintance asked me to read the letters to her half-sister's husband. The guy was super salty all October and everything happened to him and I wanted to know if he really had something or was it paranoia and I, well, normally I saw the cards and then they gave me a photo of the man and it's literally me but a little darker and skinnier and I said haha ​​what a coincidence and then I talk to the wife and my laugh becomes one of discomfort since the man is a firefighter. profession that I wanted to practice and both my uncle and my father were and out of admiration I also wanted to be one but at the last minute due to salary issues I said that it was better not and I went into computer science well going back to the boy literally the wife described him as me that is to say he is a scorpion he is a joker but serious distracted etc and also that he had an ex-wife who is a witch and well that guy also had problems with tumors that several times due to strange things they have had to operate on him and even after the operations he still has discomfort in the organs that I had in his day, except that I didn't have surgery and I was able to heal myself by a miracle (I don't recommend that either, you can go to a good doctor, etc., do it) although it didn't feel strange, it was like seeing myself in a mirror in an alternate world where instead of being a magician and computer scientist I became a firefighter like I always wanted as a child.

I heard somewhere that it was a sign of bad luck to see your double, although I didn't see it in person and I haven't had bad luck since that day. What I would say is that I feel a little strange because I am literally living with my good organs and he didn't have to have anything removed like the one who had that bad luck.
