First time feeling lonely in a long time

I don't want this to be a woe is me post but just want to vent. I was taking the bus to work today and I swear every one in that bus was with there significant others from old people to college kids to freshman in high school all happy together it felt like I took a hit to the heart seeing that and kinda soured my dayIt normally doesn't bother me seeing stuff like that but something about today reminded me what I was missing out on and just put me in a lonely moodLike I said just venting how was your day? today felt like a non-stop rush at work (food service) going to go make it better now that I left work
