Is it normal to "communicate" with yourself from the future

Hello,
I see myself in the future always as another person than I am currently which is why I sometimes write stories or questions to myself in the future. It kinda help me to exist with my isolation and to deal with any problem by having different opinions of myself in different "emotions" (I have ADD)

(I know this isn't normal: I have started to cut the first letter of people's name that act like as if they were my friends but take advantage of me, threat me often according how they feel like, etc. in real life. I know it sounds like as if I'm some edgy teenager but I always let myself threat terrible by others and if I see the letters on my arm I always remember that I should avoid that person)
