I'm betrayed by the one I trust the most

HAVE YOU EVER FELT BETRAYED? Actually, I've never been in a relationship and i have recently matured. As a consequence, I feel like this is the first time I'm betrayed. ugh! it hurts so bad. It feels as if I had been stabbed with a knife this whole time. I have never felt this way before. I'm so occupied and I can't think of anything else. I think back from time to time and my eyes waters. moreover, the person that betrays me seems to be totally unaware of my feelings. I wanted to cry, but my pride stopped me from doing so. on the other hand my instincts told me:' if she considered you a friend, she would have told you. Now that she don't, why should you bother yourself with it? it was not an easy experience but as a human, we are flexible and i adjusted accordingly. During those days, I once again decided not to trust anyone again. And i told myself, 'You are a strong girl, you will get through this.' This is how I moved on I have a friend whom I believed will stand by my side even if the world turn it's back on me. I really love her and i believe she loves me too. it was the first day of my college that we first met. we bumped into each other in English calss and in that way, we get acquainted. it turns out we're in the same situation(meaning we don't have a single friend when we first went). we then become great friends and return home together, although my home was a few kilometres away.
