Well, for quite some time I thought i got as far that i thought i wouldn't be needing to cry anymore. Before a 2 months ago now, i couldn't remember when the last time was i cried, maybe it was from when i was 10 or so. People died, sad things happened, and yet i was capable of not feeling to much about it. I was glad i could ban extreme sadness out, but yet i was kinda getting scared of myself either i wasn't becoming some kind of crazy sociopath that no longer was human, but just mind. Like what they say about serial killers on tv. But then, 2 months ago, we just had a nest of so cute small cats. One of them was not doing very well, it got bad rather quick and the mother gave up on it, so we took it in and i took care of it. I did so much for that small cute cat, i spent endless time getting it to eat and drink, it was always with me when i was awake (i move in my sleep and i was afraid i could suffocate or crush it while lseeping, so i didn't put it with me in bed) so i could keep it warm enough. I shortened my nights so drastically that i even went to 3.5 hours just so i could keep it as often warm and in company so it would get better and wouldn't feel lonely. The kitten got a bit better and that hope kept me going. And then suddenly in an evening, it got worse really quickly, to the point where i just got the infraredlight and put it on it hoping it would change something. You saw the life just getting drained out of the little cat untill it stopped giving signs of life. I left the lamp on for 5 minutes after, just to make sure if it wasn't dead already, the death would still be as comfortable as possible. I felt getting weaker, but i was still more or less ok. But then when it started shitting itself and i cleaned it up to keep the body a bit clean, i started to feel terrible, but i still had the power to focus on something differently and carry on. Then some white-yellowish slime came out of the nose (no clue what it could have been, it wasn't boogers or so) and i had to sweep it of the cute face i had cared for all that time, i felt i was on the edge. I took a break and walked away, to calm myself a bit and then the girlfriend of my brother walks in, sees my face isn't as happy as usually and asks what's wrong. That's the moment i cracked. Just the simple question "is everything alright?". I just went out and cried. It was a weird feeling. I felt weaker than i thought because i thought i was finally able to ban the extreme sadnessfeeling out and that prooved wrong, yet i was glad that i wasn't able to do it, i felt more human again.
Anyway, story short: don't feel necesarilly a creep because you can hold emotions for some time, even when you're capable of not expressing them for some time, they'll still be there and on a moment when everything combines, you'll still crack for your emotions.
I hope this helped a bit
