I Keep Thinking that I have Diseases and Conditions and Obsess Over it, and Believe I'll Die Soon?

ok ive had that feeling before relax breath in and breath out from what ive heard salt is something our bodies need to survive and i eat salty foods all the time and im perfectly healthy. ur not gonna die. stop looking up diseases and crap and have fun be a kid. my family says that crap all the time i was in the same situation i just stopped thinkin about all that and nothing bad or serious has happened to me i have worried about havin diabetes also dont worry about it ppl eat salty foods and crap all the time and dont get diabetes. unless ur 300 pounds and eat sweet junk food 24/7 ur probably not gonna have diabetes. im 21 and i worried myself to death about that stuff when I was ur age till i finally just stopped thinkin about it and i was happy again and ur 13 ur just paranoid u dont have any diseases i can already tell ur perfectly healthy.
