Social Media makes me feel rejected?

[confused]

I know It's only social media and that I shouldn't take it seriously, but sometiems I do when it comes down to people that I actually know. Well I've been dealing with a social anxiety disorder for a few years now, ever since I was bullied as a child. So it's really hard for me to make friends. It's weird how i can't connect with people and be friends with them. Like I have a few people who are accaqutises but that's it. Well I have an Instagram page and lately some people who I know haven't followed me back. Two girls from my school who are friends with my friends, accepted my friend request but didn't follow me back. I didn't take it seriously because I told myself "Well they're not my friends, and they don't really know me so I guess it's okay"...it did hurt my feelings a little.

Then what really hurt me was my boss for my online internship. I'm an intern at this website where I write articles for the website and there are a group of girls who do the same, it's a program for young adult journalist. Well I talk to my boss and the rest of the group on a weekly basis for our conference calls and we email each other almost every day for work related things. Well I followed her and the companies instagram page and they didn't follow me back :/ I know that sometimes bosses don't want to follow or friend their employees online, but she's friends and follows everyone else from my job...just not me. It just makes me feel rejected.

Like I'll never be able to be friends with people. Another girl whose intern did the same thing to me, she didn't follow me back on instagram. I know it's just social media....I know, but I feel like when people do things like it just means that I'm not important enough, I'm not their friend, and that we have relationship what so ever. I'm trying really hard to break out of this social anxiety, but it's really hard for me to. I should probably just stay off of social media, but I need it for my job (the one that doesn't follow me back -__-)
