I got really bad anxiety starting when I was 33 it kinda came out of nowhere. I never had it before I until 33. I got blood work done and turned out I have a tumor on my pituitary gland. My anxiety was unmanageable for around 5 months or so then tapered off and Gradually got better. I’ve been off my meds for the tumor for a long time and my anxiety seems to have come back like it did before.
