I Am not pooping...what do i do to make me go?

I have been struggling with this for a few years. I just don’t go sometimes it every other day sometimes it’s every other week. I have done enemas, laxatives, stool softeners, pure flax seed oil, dieter’s tea, benifiber, some foamy thing to clean the wall of your colon, drinking a gallon of water a day, eating only fruits and veggies, yet NOTHING. My mom says I’m to young for a colonoscopy and i don’t need it. A mage therapist showed me where it was on my side and how to mage it and make it move. While doing that i felt all the way to where it begins it is ROCK SOLID ALL THE WAY! My doctor said benifiber or an enema neither worked. I got this health food stuff it was a like casagrada something it was some kind of bark but it made your colon spasm and contract and with that i had been going every other day so but then i ran out and its way to expensive to keep buying and it said i shouldn’t use it for dependency and i was so i need to know what to do. I always feel like people notice and my stomach is always twisting. I always have an extra bulge on my stomach and i want it to go down someone please help.
