Hello I am a 20yr old male who is healthy and active. I need help I have been told by my doctor I have anxiety these are my symptoms constant head pressure sometimes headaches, eye strain and pain, stiff neck, sore and aching muscles, body feels heavy a lot, feeling constantly out of it like I'm high all the time. About two months ago I started getting lightheaded and feeling out of it and it hasn't went away im so scared. I also get very lightheaded after I eat and feel like I am going to pass out I have had almost any blood test you can think of including diabetes, I have also had two ekgs and go for a stress test and ct tomorrow I am so scared that they are going to find a tumor of heart problems I cannot stop panicking and worrying no matter what I do I have been on lexapro for about 3 weeks now 10mg a day seems to help my mood but that's it. The thing that worries me the most is that there is actually something very wrong with me the out of it feeling constantly is starting to really scare me I am also off balance all the time and have trouble with words and using my hands sometimes any feedback would be appreciated thank you.
