Strange feelings at night

Sometime I check my high school friends life on social media and I get such a weird and strange feeling. It is just so weird how we were once so close, our lives, dreams, and thinking was identical. Today I am that weirdo girl who is still single, flew to Canada, and is still living the single life, me and only me to worry about, watching TV at night, and doing whatever whenever.. While they all matured, went down the normal path of getting married and having kids.. they care for a family and have become one of those women, if you know what I mean ..

Not that i am longing to have their life, but sometimes i wonder why am I still living the same life but their life changed so much.. and I don't mean that my life hasn't, that's CRAZY to say.. I only mean that I am still single, studying this and doing that just like when we were all young. While they have become one of those "mature" people we used to know when we were at the same age.. because now, i feel we aren't at the same age. I feel I was locked up in that high school phase, stuck in that life, while they continued to grow up..

Such a strange feeling when I viewed the profile of the person was my best friend once in high school. How entirely different we are now and when did we grow that different anyway?
