Is this brain fog?

Lately ( past few months )I’ve been really anxious/ depressed and I’ve started having these really weird symptoms. I literally don’t feel real like I’m living in a dream and my head doesn’t hurt but it’s just really uncomfortable. It’s like this odd pressure tingly weird sensation. Over the counter medicine doesn’t help so I don’t think it’s like a headache or anything and I’ve been to the doctor and gotten an mri and nothing is wrong in my brain physically. The feeling goes away when I’m distracted sometimes but most of the time I’m focused on this odd feeling of not feeling real and this weird pressure sensation in my head. My life feels like it revolves around it at this point and I’m getting more disturbed by it with each day that passes. Is this brain fog? When I look up my symptoms that’s what comes up but when I read the synopsis on it it doesn’t seem like what I’m feeling. Sorry this turned into a vent post my mom thinks I’m crazy and isn’t rly taking me seriously.
