The real world is about sucking it up and dealing with it. Practise talking to people, it’s the only way you’ll get used to it.
Hiding away won’t help.
At 23 you need to join the real world.
Trust me on that.
I’m an expert at avoiding people.
Making eye contact (not staring!) smiling and saying “hello”, genuinely listening, and doing the best you can at your job.
Fake it til you make it, I’m still doing this.
I’m socially awkward, shy & years older than you, if I can have a job so can you.
