Fatigue and dizziness need answers

Fatigue and dizziness need advice

I need some advice because my anxiety has been really bad lately because of how I have been feeling.I have zero energy. I will admit my sleep pattern isn’t the best but it’s improved from how bad it used to be I sleep 6-8 hours every day and I’ve just returned to the gym 8 days ago after a small injury.

I have vertigo sometimes and I just feel rlly shaky and this isn’t caused from anxiety I just feel really tired and slightly dizzy. I had an ECG scan for my heart as I thought there may be something wrong but the results came back fine but I’m still getting chest pains rapid heart beat and sometimes palpitations.Like even now writing this I have a pain coming up from my left side to my neck just sharp shooting pains.

I will admit I spend most days in the house sometimes 2 days at a time not even leaving the house. I need help I need answers I’ve been trying to keep a cool mind just getting on with it but I can’t ignore it anymore and feel something may actually be wrong
