Im so lost in myself because although i have medical professionals to back me up that nothing is wrong with me,and I know im not going to die like i fear ( i have health anxiety) my body feels otherwise. I spent about 1 1/2 years trying to figure out why i feel the way i do . LOTS AND LOTS OF BLOOD WORK urinalysis, cat scans , ekgs, mri,s all have come back normal. I just started therapy but i am already discouraged that it will work. I refused to take medication because i was afraid and the doctor told me it would be fine as long as started therapy and i have. Im very sensitive to foreign sensations they send me into a panic even if its familiar. My biggest anxiety symptom and my worst is derealization i cant seem to shake it making my anxiety and panic worse. I fear because it is constantly there and it makes my vision weird maybe it is a brain tumor .i feel numb inside like literally numb .Its like how do I know im not going crazy? will it ever go away? Is this normal? Is ita brain tumor? pleasy advice would be great i feel so lost afraid sad anxious . thank you for taking the time to read this
