Hi. I'm A 29 Year Old Male With Severe Health

Hi. I'm a 29 year old male with severe health anxiety. Since Covid-19 it has been unbearable. Every minute of the day I'm terrified of having a heart attack. I've been researching daily about all sorts of things and I've been put off everything. Every medication the Dr might give me I'm too scared to take due to the risks on the heart. It seems eveything effects the Heart even mild sedatives, antidepressants pain killers, protein powder etc. I'm in a massive dilemma at the moment. I'm suffering with terrible tooth ache but don't want to take a strong pain killer (tramadol) as I know they work well for pain but I'm too scared about the risks. (I research into everything) so I've been sat here in pain for ages because I'd rather the pain than the side effects of medication. Also I suffer from extreme anxiety, I used to be in sertraline but I came off them a year ago because of the long term risks. I have bad insomnia also, the Dr gave me some sleeping tablets a while ago but I still haven't taken any yet as I read that you're 5 times more likely to die in the next 7 years if you take them, also it could cause a heart attack? My health anxiety didn't used to be this bad at all, if I needed to take a tablet to help me I'd just take it without worrying, but not even if I take something for anxiety it would make me more anxious becuase I would think of things like 'what if this is bad for my heart' 'what if this can kill me' so no matter what I take, what I do or what I eat, I cannot escape this anxiety and it is affecting my daily life massively to the point I'm terrified of basically everything. I do get chest pains sometimes and I'm not sure if that's anxiety, gastro or indigestion pain heart problems due to the fact I've been a smoker on and off for 8 years (currently cut down to 3 per day as I'm terrified of the side effects) or am I just reading too much into everything. I can't relax. Ever. Do you think that this could have something to do with the fact I used marijuana on and off medicinal use only for 6 years? I don't know what to do anymore. Everything that I do or eat I am terrified that it will have a negative effect on my heart as everything seems to these days. I didn't realise that most medication is bad for the heart. Especially anxiety meds, I thought if anyrhing, they wouldn't be bad for the heart as its calming down your nerves and central nervous system etc. Why is everything bad for the heart? 29 years old I shouldn't just die of a heart attack should I? Is it safe to take a sleeping pill a few times a year? Or will that still make it more likely for me to drop dead? What if I don't wake up? I'm sorry to go on, it's Sunday so I can't phone the Doctor up until tomorrow to book an appointment. I need peace of mind.
