I’ve been tired all my life

Hello, this is my first time seeking help online because I’m having a crisis. I’m 18 years old and I’m tired all the time. This is not your usual ‘tired’ from running a long day at school or work, its a constant exhaustion. I feel like this is ruining my future, my relationships and my life.

It all started when I was little, I wasnt as active as the kids in my class, I didn’t have the energy for extra curricular activities or to go out with friends. I would usually come from school exhausted and I would sleep for hours and waking up with headaches.

This continued as I grew, my social life was literally inexistent. I was still a great student, I had to push myself to study, but it hasnt a heavy amount of studying so it wasnt a big deal at that time.

When I got into high school, everything changed. My school was one hour away by bus and the bus schedule was horrible, which meant 1:40h to do nothing after school, usually freezing at the bus station in winter. I would come home exhausted, I couldnt do anything, my body would feel cold and useless. Even when I wanted to study, I couldn’t, I used to play brown noise just to concentrate but my brain was just trying to get rest.

All my life my mom had this hatred for me because I was lazy, I didn’t do house chores and I slept all day or did nothing. When I finally told her, she told me I was just lazy. But that wasnt true, I wanted to do stuff, I wanted to be like my girl classmates that went shopping and on coffee dates with their girl friends. I got into a depression because of it, my room was a mess, I skipped school more and more often because I was too tired to wake up. I usually woke up with headaches that continued for days without stopping.

I needed help, I wanted to get better, I wanted to go out with my boyfriend on walks, I wanted to work out to get rid of all the weight I gained from practically rotting away, I wanted to get into my dream school etc. But I couldn’t do it because I was so tired.

I had brain fog, I usually got dizzy and my head was hurting. I couldn’t do basic things anymore, I felt like a failure.

I went to the doctor, she said that I may have low iron, but after some tests it came back normal. After another set of tests it said I’m vitamin B12 deficient, I started taking B12 vitamins but my condition wasnt excelent, after 4 months of taking it, nothing really changed, only my headaches were less frequent. I feel like something is wrong, and its something else. My doctor told me to take the pills only for 2 months, and it will get better, but it isnt getting better… I dont know how a normal person can be energised, or do basic stuff. I lied to myself that the pills would magically work, but I feel like I’m sleeking again. I want to have a normal life, to live like a teenager, all my friends are secretly hating me because I cant go anywhere, I feel like a vegetable. I do nothing all day. It destroys my life, I put down so many hobbies because I just get burned out.

I get burned out from everything, from reading, from studying, from paining or drawing etc. Its exhausting… I hate this life

If you have any idea how to solve this, please let me know.
