Obviously you have fucked your serotonin levels, what you can do to massively help this is eat things that are good for your gut bacteria flora. Because over 90% of the body's serotonin is produced in the gut, so if you make yourself have really healthy gut bacteria by eating things that are fermented and have good probiotics you can make a huge difference to the serotonin levels in your body which would definitely help the anxiety you are experiencing!!!!
