For things that don't require an apology. You can barely say "hello" without finding a reason to say "sorry." As if your mere existence is an inconvenience.
Sometimes you get so anxious in front of other people that you check your phone for messages. Sometimes, you even pretend to be texting when you're actually not.
You have such a tough time accepting that you are a great and worthy person that you awkwardly deflect every compliment you get. You can never muster the confidence to just say, "Thank you."
No matter how hard you work to achieve a goal, you always attribute your success to "luck" or "being blessed." You completely dismiss your skill and determination. Guess what? It's probably not luck, bub.
You'd rather dig a hole and stick your head in it than stand up for yourself or even disagree with someone. Like your opinions don't matter. They do!
You hate making decisions for others. If someone asks you where you want to go to lunch, you always answer, "I dunno, wherever YOU wanna go..."
A side-effect of having a low self-image is fatigue. As such, you ALWAYS BE NAPPING.
You never feel like you're good enough, smart enough or pretty enough. Literally anything can set you off into a tailspin.
Your first thought is, "Are they hitting on me?" Followed by, "Why would anyone ever hit on me?" Because they like you, that's why!
Meeting new people stresses you out. You put on your best face, but you're absolutely sure you're going to do something weird and the person is going to find out you're a freak.
Plot twist: We're all freaks!
