You are more likely to be ok than not and worrying now will not help. Focus on how you are feeling right now, check in with yourself and then find something nice to do or think about instead.
(That’s what works for me - most of the time.)
Each bout of covid brings with it a higher risk of long covid and increased risk of cardiovascular disease. Unfortunately this is true the world over and is infuriating that little is now done to reduce spread and how little is being invested in new vaccines/treatments compared to 2020 when we’re in a viral arms race.
BUT…the increased risk depends on a lot of things and you are young and I’m guessing haven’t had severe disease before (bigger risk) and just because the risk is increased doesn’t mean it is increased massively. (If you said “the risk is doubled” that sounds scary but if the risk was 1 in 1000 and doubled to 2 in 1000 is not actually a massive increase in risk and not as scary as it sounds).
Its is bollocks that you need to have severe disease to be affected though - even people with mild disease can get post viral symptoms. Underlying conditions could increase the risk.
But the chances of you being severely ill are low and the chance of getting treated if you need it is getting higher as the disease is further understood.
You have a very different risk factor than say an 80 year old with type 1 diabetes and chronic heart disease.
Post viral conditions are common with even the common cold and with flu etc. Not many people worried about them before covid although they can be life changing. (It’s a popular misconception that you need to catch lots of viruses to build your immune system).
I have health anxiety too and I find being better informed helps more then just people saying “nah don’t worry”…lol.
I’m avoiding covid, flu and all lurgy as much as possible and still masking and meeting outside where possible but we have to accept living in society brings risks. I’m hopeful for the future.
