Hello I have anxiety and I am really worried to do anything I keep getting physical symptons such as headaches, dizzinies, tiredness, heart racing and earlier when I woke up I had a nose bleed. I have had a ecg which came back practically normal and I have had my head checked out about a week ago at the hospital and they think nothing is wrong but I feel so dazed and scared and I can't stop thinking 'what if the doctors has missed something' please help, I'm so scared and I also keep having panic attacks. I keep worrying I have something serverly wrong such as a brain tumour or brain hemorrhage,
Please help
