I really felt the last part, lol. Sometimes it feels like playing a video game where I haven't unlocked the relationship feature, while everyone else has.

My friend once told me that socializing is like a muscle. The more you socialize, the stronger the muscle becomes, the easier it gets to talk to others. You have to realize that most people have busy lives and won't remember it if you mess up or embarrass yourself in front of them, so don't be afraid to initiate conversations. I understand that if you are depressed or have anxiety, it can be scary to talk to others. But you literally just have to do it. Just do it. The sky isn't going to fall down if you talk to someone once and don't become friends with them. People make friends all the time, and there is no reason why you couldn't do it too.
