2 months ago I had a panic attack and since then my anxiety has been really bad I felt really lightheaded and fatigued and it has made belive there is something wrong with me and it has been getting me worried so I went to the doctor got blood pressure and blood taken and they came back normal so it was put down to anxiety after that I started eating healthier, getting better sleep and getting more exercise and I cut down on alchol but I still feel weak and fatigued.

I dont know what to do I dont want to go back to the doctor because everything was checked.

Could It be my anxiety thats causing me to think this and make it worse ???
