Slight backstory: I'm looking for a job  because I'm taking a little time away from college classes and my parents are pushing me to get a job which is understandable, but I'll get back to that. So yesterday I had a rush of "let's do it" mindset so I applied for a few jobs and I made an online dating profile; anyway, one of the employers asked if I can come to an interview and I'm just panicky af.
Like, I'm so nervous and convinced that I'd be terrible for the job and that it's all going to end up in a huge disappointment. Also, I'm so terribly anxious about the thought of people seeing me as I work and I'm so afraid of embarassing myself, even if it's in front of strangers. 
On top of all that, lately I've been so unmotivated and feeling low about myself and about everything, and I hide it all from my family, and all they see is me being lazy and a burden, and I don't know how to push myself to calm down and go on that interview and just keep the anxiety reined in.
