Started having anxiety 24/7 like 3 weeks ago there’s always a feeling of tension in my head like I have a headache but no pain just tension my blood pressure is normal and lately I’ve been thinking that I might have a brain issue and that has also increased anxiety because when I feel the head tension I think to myself “what if I have a brain tumor or something” and I’ve had this feeling all day everyday kinda makes me feel like I don’t have control over my life and why would I develop anxiety like this out of nowhere?
