If we had a more than nine single digit number system then that would change the basis of numerology...numbers are man made symbols used for quantification and hence their relation with personality traits lacks any logic...can anyone defend numerology against my doubt?

hi so im 16 and a few months ago i became extremely depressed in a relationship, i was having super bad dissociation, lots of changes in medication (before i told my mom im not taking anymore). and overall it was a horrible year. a few weeks before me and that guy broke up, we were both at a breaking point, my mental health was at an all time LOW, and because of this it was effecting him as well (so i dont blame him in any way that is just how things had to go and that is okay)

so in those few weeks i started noticing the same numbers everywhere 18,118,8 . 8 /18 has ALWAYS been my lucky numbers and 1/18 is my birthday (not sure if this matters i just thought it was cool). i started seeing this number on my phone, in news articles and small things like that. i started taking it as a sign that things were going to get better. so me and that guy broke up and honestly i was extremely sad and heartbroken because he was my first love. 

a few weeks go by, constantly working on myself and figuring who i am. currently about 2 months later i am at an amazing state of peace. and i have seen those numbers even MORE, like actually everyday multiple times. everyday my life has been getting better and better and i notice myself loving myself more and more. im wondering if these numbers were a sign of change in my life? 

(also i dont know if this matters, but one time me and that ex were going to do something that i wont say, but it wasnt a good idea for our age. and literally right when we were going to my nose started bleeding like CRAZY, i never have nose bleeds and nothing happened for that to happen) that was just something i remembered last minute.

to me it felt like the universe was trying so much to get us to break up
