Is it normal i still don't have decent health?

I'm almost 27 but when I was 22, I got a few serious health conditions that give me a multitude of severe symptoms.

These symptoms prevent me from living life as a normal person and so, I have been unable to hang out with friends, go on a vacation or even take a drive anywhere. On top of that, I am unable to do small every-day tasks that everyone has to do without pain in the way. This pain isn't mild or moderate, this pain is extremely severe and actually feels as if my entire body is on fire and that I am being burned alive. This pain doesn't go away and is always there. I lie awake at night from this pain and I am unable to ever rest. I don't want to live like this and it also hurts me emotionally as being in pain for so long would obviously cause this but I also know that almost all my twenties are gone because of the pain. I always wonder if this is my life. If my life is to just be in serious pain all the time and never be able to smile, laugh or have an ounce of fun ever again. It's been years since I had two seconds where I felt "okay".

I have to continue to work since I got this years back even though work makes it even worse. At work, this pain isn't serious pain, it is a billion times as serious and many times I have to go to the bathroom to cry because it hurts so much. My doctors know this and keep trying to find a cure but my parents don't attempt to understand as they have always been stubborn with me since as long as I can remember.

When I first got this pain , I also lost my boyfriend of three years because I couldn't give him sex anymore from the pain and he basically just broke up with me by text and said he's sorry but he needs sex.

I also lost my friend in a car accident five months after he left me. She wasn't my best friend but it still hurt lots.

I've been suicidal from all the pain and it has also made me crazy as I never cried in public before but I now cry at my work when I'm just in pain. I don't want to cry, I bite my lip so hard it sometimes bleeds but that doesn't stop the tears.

Is this normal? I just want to be alive again and enjoy life.

Before I had this, I also lost two relatives so it's been really rough. I just wait for a silver lining but it never seems to come. :,( I know this is long but I hope someone actually somehow wants to respond. Thank you as it took me everything to write this.
