First of all, let me say that I am so sorry for your loss. I know that pure text doesn't translate well and it's hard to express emotions in this limited environment, but reading your posts the past few days have hit me. I wish there was something I could say or do, but just realize you have a friend here if you ever are in need.
Secondly, right now you just went through a very hard thing that many people either struggle with or inevitably will. At this point in time, it makes sense to look at everything and rexamine where you are and what you want. Just remember, sometimes what we feel during powerful and emotional stages doesn't always reflect what we really want or hope for. Think things over. Give it time. Allow yourself time to grieve and process things. Maybe seeking the love of your life and giving up hrt would be the right move? Maybe you could go forward as a transwoman and still conquer the loneliness that you feel? These are questions that only you can answer with deep thought and time. Don't feel the need to rush. Make sure you are doing what's right for you. There is no time table for these things. Do what's best for Natalia whatever that may be.
Again, I'm very very sorry you are going through this.
