Hi!

I'm seeking advice regarding the physical manifestations of anxiety. I'm 24 female, I've struggled with atypical depression and GAD for almost 4 years now (+ severe social anxiety in HS, but that's long gone now), but I'm overall healthy, I exercise a lot and eat good food, also no caffeine, smoking or alcohol. Right now i'm taking only 200 mg Lamictal for the depression. I've started seeing my psychiatrist in April this year (after 1 year anxiety and depression free) and she'd put me on vortioxetine, which was good for the anxiety but made me gain a lot of weight and made me tired all the time so i stopped it, then she suggested Gabapentin, but I refused it since I know that withdrawals are hell, then I tried going to another doc which put me on SSRI - fluvoxamine, but this had side effects I couldn't bare (more anxiety, dizziness, tiredness, blurred vision and so on) and also prescribed Tofisopam, which I take now when needed. 

The problem is that my anxiety is bad rn in terms of the physical manifestation of it - I have constant nausea, which prevents me from doing many things. Until now I had summer break from uni and I worked from home, but now I'm changing jobs, which I'm really looking forward to, but I will have to be in the lab every day. I tried different breathing techniques to calm me down, mint and chamomile tea, distracting myself, all of which provide temporal relief and also some medications such as dimenhydrinate and metoclopramide hydrochloride but they have side effects as well and it's not good that I take them while on Lamictal. Honestly I'm scared of going to class because I always think how I'm gonna be sick and I try to sit close to the door, I go later than the others so I don't have to talk to them etc. I take Tofisopam before I go to class and will take more if I feel the anxiety creeping in but I know I can't go on like this. Does anyone know anything I could do so I don't feel the nausea that much? It's driving me crazy for several weeks now and I couldn't seem to make it better in any way, I also seem to have it while doing enjoyable things such as when I'm cycling or reading or when I'm with friends or with my SO. Thanks so much in advance!

tl;dr - Severe nausea because of anxiety, seeking advice how to handle it
