Two days ago I've used Epiduo Gel for the first time for my face, shoulders, chest and back, as prescribed by a dermatologist.

Besides that, yesterday I took about a spoonful and a half of protein powder for the first time after working out (I work out about 3 times per week, 15 minutes, mostly muscle strengthening, not including walks). Today I took about a spoonful (didn't get to work out today). Both days I mixed it into cold lactose-free milk and ate with cornflakes as I suspect I'm lactose sensitive (I can consume some amount of dairy without my stomach hurting).

These days I've been feeling very anxious, especially today. My stomach hurt and I've had bad frequent bowel movements, which somewhat alleviated that anxiety, but it's still there. I know my stomach gets sensitive due to anxiety but I don't think it's ever happened the other way around - do you think that might be what's happening?

I thought I'd be fine taking protein powder with lactose-free milk because it'd be like regular milk lactose-wise, which I usually can handle. Is that not the case? Does the skin gel have anything to do with it? I am also taking Sertraline (Zoloft) 100mg after the meal.

Sorry for the messy 'clues', I'm really just trying to piece this together as I thought my anxiety was getting better after a period of intense anxiety a few weeks ago.

Thank you for taking the time to read, and please help me if you can, even if it's to tell me there's no correlation between the things.
