A few days ago, I was sitting in one of the train stations I use for my daily commute, thinking about work and some problems I still need to solve. Then I noticed someone right in front of me, and from the back she looked like the source of those horrible emails I used to receive until a few years ago.
I know where this "source" of bad wishes works, and this station is probably also used to commute there, so it was quite possible that this was it. 
Up until a year ago, I think I would have panicked and probably run away at this point, but this time I was actually calm and reacted much more rationally, leaving the place, taking another train and not even looking back to confirm my suspicions.
In the end I never knew if it was the stalker or not, but fortunately it doesn't seem to matter anymore, I find it very nice that he doesn't have any power over me anymore and I can live my life in peace after all those years where I felt his shadow looming over me.
I am quite proud of myself, even if this may seem like something easy or natural for other people to achieve, for me it took quite a long time to reach this point, so I think I am justified in enjoying it. Good for me!
