Please help

Hello, I am 26 years old and I have anxiety. Thing is, lately I've been getting pressure on my nose bridge and light headed then I start getting bad thoughts like I'mma die or if something is mentally wrong with me. I know I need to get checked by the doctor and have a physical done. I just don't know if my confusion and pressure is related to my anxiety. It's driving me crazy and maybe you guys can provide me with some support . I don't like being in this state of mind where I feel like I'm better off dead. I don't have to feel this way anymore. I don't feel normal, no I would never hurt myself. It's just idk how to deal with this anymore. Thank you.
