I am in constant physical pain

I don't really know if it's the best subreddit for this but I desperately need to talk about it.

I (15F) don't know what a life without pain is. Everyday there's a problem and somewhere hurting.

My parents are Slavic and grew up poor without any doctor or medical help so now they're projecting that on me.

They also think that I lie to get attention (which is not true)

I ended up not telling anything to anyone despite hurting constantly and it got worse, I had a very bad hip pain for almost 2 years, couldn't walk properly and sometimes not at all. For 2 years. My parents only made me an appointment recently when I really couldn't walk AT ALL and nothing?? The doctors couldn't find anything so obviously, my parents now think that I'm lying for that too.

I also have astigmatism (self diagnosis)

I only discovered that recently.

I have really really bad headaches that sometimes can go up to 2 full days. For years and years... My parents always told me to just take some ibuprofen and go to sleep but I can't do it anymore. I have school and exams, I can't have my head constantly hurting.

I'm begging them to make an appointment with an ophthalmologist and finally prescribe me something, anything to make it stop.

They just won't listen. They still think that I'm lying despite seeing me roll to the floor in pain.

Crying in pain

It's just... Unbearable.

I even cut off friends because they wouldn't take me seriously either. I constantly am in pain and I try my best to hide it, I thought I could trust them and talk about it with them but after that the only thing they did was complain because "I'm in a bad mood"

I'm HURTING. What can't people understand, seriously??

Only my boyfriend understands and tries his best to take care of me, but now I'm feeling guilty...

I often apologize for it and I sometimes try to hide it from him.

He told me that I should do my appointments alone and take responsibility but it's not that easy.

Now I don't know what to do.

Right now all my back hurts really bad and I've got a headache since this morning. I'm just so tired.
