fatigue and feeling unwell.

I'm a hypochondriac so every health related thing I say should be taken with a grain if salt (maybe I shouldnt say that lol), but lately the fatigue I've been feeling has been kinda extreme? like I really dont have the energy to do anything. perhaps it could be my poor diet, lack of exercise and horrible sleep schedule (which are all plausible reasons for your body to feel like shit) or (what I've convinced myself to believe is true) I'm dying from some type of cancer and since my body is fighting it off so I have no energy!!! man, I sure do love thinking like this. also I'm scared because I feel like my lymph nodes might be swollen but I dont know if they are ir if the w azz y my neck feels is actually totally normal and I'm just stupid. but I know that blowing things off like this could be unsafe if there IS actually something wrong with me. I dont know. I'm just scared and no one takes my health scared seriously because of my hypochondria. which yk, makes sense, but it also really sucks. I feel like I should call a doctor, but I dont have my own insurance and I'm sick of going to the fuckin pediatrician because I'm FUCKIN 19 I SHOULDNT BE GOIN TO THE DAMN KID DOCTOR. I need someone who can talk to me like an ADULT and not sweet talk everything and ignore my concerns. I really dont know what to do. I'm  just so lost and I'm feeling unwell on a DAILY basis. A DAILY BASIS. maybe I'm truly unwell, maybe my brain is playing some fucked up tricks on me. I dont know, but I have to do something eventually. I cant keep waiting around for answers like this.
