I've been experiencing pain in the stomach for some years now but this recent week I've just been really alarmed as I'm writing this I am honestly scared of even going to sleep, I've been feeling pain in the sides and the doctors told me that it's just some kidney sand but I've been on alert the entire week, I've been short of breath and I just am worried that I may have something and that I may not wake up, idk if I'm hypochondriac or what but if anyone has any tips to calm me or just had a similar experience it would help
