Early ASC and Moon void. 2 strictures do stand out.
Not much happening in the chart. Sun in fall too. You are not in a good position right now to get a new job.
But if you reject any jobs offer then how will you find a new job?
In regards to this current job, maybe you should try to look at it differently. You say you are shy, and reserved not talkative in a clothes shop... Maybe try putting on an act, because in a customer orientated job many times one needs to be very cheerful and happy, always smiling. Practice being cheerful, smile at people, approach your customers yourself and just ask about their day... tell them you are there to help them... Just be out and about, don't sit in the corner and look miserable and shy. Think positively and be that positive cheerful guy. Also have some dance/disco music playing in the shop, that will be helpful to bring some positivity into everyone.
Change your attitude - do not think 'I'm shy, I'm reserved, I can't do my job... instead think positively ' I can do this job, I am positive, I am cheerful, I am approachable, customers love talking with me...'
I hope this helps, even a little bit. Think of yourself as an actor and this shop is your stage... go out and play this role of a sunny carefree guy.
all the best!
