Not sure how to trust my instincts with my health

tell me why… idk if this is just me but i’m so scared i have ovarian cancer, kidney stone, kidney failure, UTI, hernia, or something wrong that’s making my lower stomach to my inner thigh and pelvic area. i have an uncomfortable feeling. it was hurting more last night then it is today… everytime i pee it doesn’t hurt but i somewhat still get the uncomfortable feeling down there and feeling in stomach. i’ve been googling and idk what to do because i’m scared of the doctors and i haven’t had a physical like in 2 years and i’m like scared if i go to a physicial i will have something wrong with me like i have cancer or something that i don’t know about. something tells me the pain tho in general is something gastrointestinal related but idk if could mean i have pain down “there”…. i took a tylenol last night it helped a little but then it still kinda occurred and i took a tum and it’s still the same i think it’s still occurring since i’m so hyper focused about it. idk i’m just like ugh my OCD was doing so well i just can’t tell what it is or if something is wrong i’m just scared :( i hate when having certain pains i freak out.

Starting to think I have unresolved childhood trauma unfortunately. Health OCD is also driving my absolutely crazy but I'm too scared to go to my doctor. I worry about diabetes, illnesses, cancer, skin problems, etc. I just hope everything works out in the end. Right now I just can't do the things I love doing because I'm constantly worrying about everything. All of my worries are exacerbated and I just can't keep them away. They only come back.

I went to internal medicine today, and i'm not perfectly healthy, My liver is a little bit fat, I have to lose weight so thats okay, also I have gallsand, which is not gallstone yet but it can become that if its not treated. Now im like these arent big problems but when i heard these I started to overthink and think about the worse that I will have gallstones cause the doctor said I have it cause it runs in my family(my mother/grandmother and uncle had it) and I just think that it wont go away, and even if i doesn I will be worried all year if it came back. Im just so afraid. Also they said I should go get a blood check, but I said i will hesitate now cause last time i almost fainted and felt horrible the whole day, and now i hear from people i know that they went and they felt sick and vomited there. But the overthinking comes from me thinking if these little symptoms I experienced which I thought its because of anxiety, was because of health issues then the other symptoms I experience sometimes (headache and lightheadedness) are there cause of another health issue, and im worrying about my health, im afraid of death, i keep imagining myself if they tell me that i have terminal illness or something really bad and i dont know how to handle it. Now i feel nausea and i would say its because of stress but i keep thinking that its because of the health issues I have...I don't know how to handle this fear, if you ask others or therapists, they will say "yeah everyone is afraid of death and suffering" or "Try to think about something else" and i wont pay for advices like this...
