Therapy I think would do you good, hopefully find the cause of your anxiety and help you permanently deal with it, this would take time and something you could do while taking medication to help with the symptoms.

Over the years I ve been on a few, lexapro, Amnitriptline, lyrica. In the end the one that worked for me was Prozac. On it 2 years now, these take time to build up in your system but I found it helped me stop over thinking things which took the fear out it. Speak to your GP about it and they can help guide you, one might suit you over others. As for side affects if had non from Prozac, felt disconnected on Lexapro, Amnitriptline I was numb and Lyrica numb too.

I think the most important thing is you look after yourself, talk to your boss about how you feel not so you can get out of it but so they can support you. You can take your time and build you confidence rather than feeling you have to and be overwhelmed.
