I've had a similar issue with going back to work again, although a bit of a different story.
So I will share with you the comfort and encouragement I myself have gotten to prep for this next step in life
Finding a place where you feel safe to talk about your anxieties. Here is a good place but if you would like to be with a counsellor, someone who you feel comfortable speaking to or a positive friend, I think that is a best thing
. You mentioned you were a student, I'm sure you have free counselling at your school that you can start with. If you would like to continue to something more, you can always go from there and she/he can guide you toward that. Universities and Colleges usually have a career and counselling development department that are prepared to help students whether it be life stuff, career or academics. They're usually found in the health departments of the school. Also, there is academic advisors that can be helpful. You wouldn't think it immediately but our academic advisor for each department are also prepared to help students deal with real life stuff such as social anxiety. There is help and support all around us
. Don't be ashamed or embarassed for feeling like this, it happens to so many of us, especially when we are getting ready for adulthood. Don't feel bad, you are just figuring out who you are and what is right for you.
In saying that last part, feeling for what is right for you. You're not choosing a career in your part time job, it's merely for the sake of having money for yourself, right? So in that sense, the number of opportunities are huge. You don't need to work in customer service. Like someone mentioned above, you can work in a small office or even with a relative at their work. There are a lot of options. You can always contact a job recruitment agency (there are free ones) and tell them that you prefer not to work in a largely public job, something lower key in terms of social interaction and you'd be surprised at the opportunities around you
. You can have money and find yourself somewhere interesting to spend 8-20 hours of your week. I've had a variety of jobs in my life (10 in all already!). It's amazing all the skills you can gain from the different experiences and the friends you can make. From each job experience, we learn, we grow and we become stronger and more skilled versions of ourselves. Our confidence and self esteem grows too.
Waitressing can be a very stressful job, especially if you are already suffering with social anxiety. It's good to sometimes throw yourself in the deep end to learn to swim but I mean, if that's way too stressful, bringing us wayy more negative than positive out of the experience than clearly, it isn't the right way to go about it.
I am sure that one day you will reach a point in your life where you won't feel as anxious in social settings. Who knows, maybe one day you will even be a public speaker because you have conquered this, you never know.
One step at a time, babes, take it as slow as you want. You are getting there already. Talk to a positive friend/counsellor about it, know that you can do this like so many others have and like you have on other first highly anxious parts of your life that now you feel confident in, and let yourself be in that positive mind set of finding a job that is right for you. Know that there are jobs out there that are perfect for you just waiting for you to apply to them. Then go out there and apply to them.
I am so sure that once you will start your new job and will be feeling confident in it, you will feel yourself wanting to challenge yourself further and do a small social interaction trial that you will triumph at. Then another and another until one day, you will never feel anxious about working again. You'll get there, hun
You can do it, one step at a time
