...i need serious help... I honestly can't handle any judgement so please don't

For my entire life I've had constant stomach pains, on a scale 1-10... it's usually a constant 5. At times it'll drop to a 4. Then go to a 8 but, it never truly goes away. I am about to be 17 years old ans all it has done is get worse..... No doctor can figure out what is wrong with me...... all any doctors could find was scar tissue on my stomach liner... i have even had a couple doctors tell me there is nothing wrong with me... it is terrifying and very very painful... it keeps me from getting a job, or having a life really at all.. and I've pretty much lost all will to live.... no medications I've tried have helped.... Now trust me when I say this.. I've tried just about anything you can think of for it.. the only thing that even slightly helps is marijuana and I can't really afford that anymore and I don't know what to do anymore I'm losing all hope... I'm so tired of the pain all I ever do anymore really is curl up in a ball and cry....

and yes I am over weight now but when this all started I was not. I was a skinny active kid.. And even now I don't even over eat. I'm just fat... 240+lbs Update: I'm currently sitting in the ER waiting to see a doctor they have taken x-Rays and blood samples... if they can't figure anything out tonight I have a doctors appointment made for Monday as well I feel absolutely horrible right now ladies but thank you all for trying to help me it means the world to me I'll keep you all posted. (after ER visit) the doctor is blaming marijuana. the one thing that helps the pain. I'm fucking done with this shit idk what else to fucking do I mean fuck this shit I'm honestly to the point that if I die I just die but imma smoke weed till the end because it's the only thing keeping me from curling up in a ball and crying my eyes out 24/7 and it's the only thing to numb the pain enough for me to ear. I'm so over this. Fuck doctors. Fuck life. May's done.
