Took my first dose at 9am

Hey everyone, I’m currently fighting for my life rn at 1 am. I took my first dose of lexapro today. 10mg cut in half. I felt fine most of the day, then around 5pm my stomach started to feel disgusting. The thought of food made me want to projectile vomit. I’m taking this medicine for the fear of throwing up mind you. So terrible combo, anyway I got some food down eventually and my stomach felt meh until bedtime. I am pretty good at not throwing up, knock on wood, so I’ve been chewing gum, smelling rubbing alcohol, and I took some tums that contain ginger to supposedly help with the nausea. I just woke up like 30 minutes ago in a sweat and am fighting for my life yet again. Do you think I should push through with this medicine, my main concern is I do not have the time to “push through” this as I cannot take any time off work etc. I don’t know what to do and if I do stop taking this when will I feel better? If anyone has any tips for me please let me know, I do not want to feel like this for weeks or even a couple more days. My anxiety makes me feel nauseous but this is another level. I really need help with my health anxiety and I really wanted this to work good. I’m not the biggest fan of trial and error like this, last time I tried an ssri I passed out a week into it, which I had never had a history of passing out. (Zoloft 25mg). That was a pretty scary experience for me, but other than the passing out, I was completely symptom free leading up to it.
