Anxiety or something worse??

Bare with me this is quite long and thank you in advance for taking the time and reading this!I honestly do not know where to start... first off forgive my grammar and spelling for i am a little bit sleep deprived at the moment. About 2 months ago I decided to quit smoking both weed and cigarettes at first i quit cigarettes and then soon after was the  weed  i didnt have any urges or cravings for neither of them however about 3-4 days in of quitting weed (heavy smoker for 5-6 months)  as i was working out in my garage (dumbest thing ever with this heat) i got very dizzy and felt like i was gonna black out so i quickly threw some cold water on my face and recovered from it , soon after i showered, i was going downstairs and it hit me again ( dizziness and what not thats when i start freaking out . For the next 2 weeks or so it was ongoing dizziness, agitation, panick attacks(thinking that something is wrong with my heart i ended up getting an ekg later on and that helped relieve the panick attacks), stomach pain, chest pain, backpain, nightmares, nausea, headaches, major loss of appetite, major anxiety (and most of its symptoms) ... I didn't know what was going on I literally thought i was dying. Another two weeks pass and i slowly recover from the dizziness, my appetite is back however my stomach pain is still going and its like all over my stomack near my groin area(lower abdomen)  to the top of the abdomen and back pain aswell as headaches, burning sensations all around the body (different spots sometimes my neck,foot,arm,back) i experience numbness as well, rib cage pain mainly lowest 2, loss of sexual desire aswell went from being sexually active to not wanting to do anything...small rashes and itchiness i slso seem to feel pressure on my face and head...dry mouth and weak legs i lost a good amount of muscle because i have stopped working out for the past 2 months and wasnt eating right. I probably missed a thing or two of the symptoms that i was also having but my main concern is my stomach and back pain because i can also see and feel my stomach pulsing  and i can feel it mostly near my belly button now keep in mind im not skinny im 165 pounds 5'10"  im 20years old and this is the first time ive noticed such a thing that made me do the worst and search up my symptoms and now I can't get over the thought that i might have an aortic aneurysm (AAA)  ive done blood tests which showed everything was okay however i only did realize about the stomach pulse after my doctor visit. Should i be concerned? Whats the possibility of it happening in someone this young? It's driving me crazy i cant shake off the feeling that i have a serious illness. Doctor gave me alexa to take at a low dosage however it gave me major headaches and really the anxiety part is just me wanting to be on the safe side of knowing i dont have anything  serious because the thought of having something is whats causing my stress and panick. It has effected my life in an awful way im too scared to workout again incase i damage my oarta or something like getting dizzy again and repeating the cycle this is irrational i know im so disappointed of myself in letting this get the best of me! I have an appointment with my primary care doc in 5 days i think umma tell her about this stomach pulse but i just wanna know that im not the only one whos going or been through something similar... anything will do that i can relate to... thank you for taking the time and reading this!

You sound just like me when I am having health anxiety. I recently thought I was having a brain aneurysm. It turned out that I have mono. Now, it's definitely a good thing that you have an appointment coming up with your doctor. That's one step closer than I usually get... I also have anxiety of doctors, so I usually have to wait for my health anxiety to become more intense than my fear of doctors so I will actually go get checked out.

Write down every symptom and definitely tell her every concern. It is your health. People always made fun of me and told me that "I'm just a hypochondriac" and even made fun of me for going to get checked out when I was feeling very ill.... well, I had a fever of 103 and it was actually a very good thing that I got to a doctor when I did.

Another thing to remember is, no matter how hard it is, DO NOT Google your symptoms. Our minds are funny. I had chest pains and trouble breathing and my mom wouldn't let me go to the ER, but rather wait three weeks to see a doctor. I was fifteen and afraid, turned out it was a panic attack, but I thought worse so I googled my symptoms, saw it could potentially be a heart attack, then shortly after I magically started experiencing more symptoms like arm and leg pains, took matters into my own hands and got to the ER. Turned out I was having a panic attack and the other symptoms, were symptoms that weren't really there, but I was convinced that they were.

Just do your best to keep calm and try to take your mind off all the worries until your doctor's appointment. I can tell you're anxious because you're seeking closure (which is a part of health anxiety - you will seek closure from anyone, medical expert or not, to make sure they think you're okay). Whether or not you have an injury/illness in addition to the anxiety, know that everything will be okay. Best of wishes.

Thank you very much for taking the time to read and reply to this! You gave me such a peace of mind! Im bery thankful to you i feel better knowing im not the only that has experienced such things and as for the google symptoms you're so right about that! I wrote down my symptoms and im ready to let my doctor know of what has been going on  thank you again for the advice! Ill let you know of what my doc finds!
