well i have started but will happening during this week unpaid trial in a large company

and i went to visit to see where it was, and time myself from where my bus stop and general noisiness.
I was completley flabbergasted i am am so chuffed to bits. But my mother who has loads of negativity says to me don't get exited, it wont lead to anything, yadda
Couldn't she be a bit nicer to me just for once. I worked my butt off in college and I haven't worked in years

But she is stopping me for being excited for my own good.
so When i looked at the company today i came back completely deflated anyone that work their was in these lovely suits, and the dress code is business attire.
So i went looking at clothes and me being very heavy i am limited to what i could wear. and cost being a factor to however i would try and get some outfits this weekend.

But i suddenly hit me. That i have very little social skills in a office setting. I will be a new girl for a little while i don't want to be an over-sharing my information . I want to be polite, and fit in, and do whatever that is required of me but i am scared of letting them( co workers )seeing the real me.
At this moment i just want to this job so bad and get a good reference of them The idea of saying my name and introducing to people is scaring me at right now i agree with my mother to turn down this opportunity.

Your mother has Tall Poppy Syndrome. She can't bear to see you doing well for yourself, bettering yourself by getting a decent job - so she's doing her best to cut you off at the knees so you stay down in the place she wants you to be.

Get one over on her - go to the job, do well at the job, show her that you CAN do it and her opinion of you is irrelevant, because you've done it in spite of her attitude, and without her help.

Go on, you will be great!
