I Chew My Food Throughly. For Several Months Now, I

I chew my food throughly. For several months now, I feel it going all the way down my throat until it reaches my stomach, hurting all the way down. I take 2 20 mg prilosec daily. I drink a lot of water.The food doesn't exit my body for several days(going on for decades) I have to take stool softners and laxatives to move it along. So food gets "stuck", giving the feeling of not being able to eat any more due to being full. It gets to the point where nothing more will go in. Even the following day. I don't overeat and I eat very slow as well. I feel like I'm going to vomit. I also have pain in my lower left pelvis area (right in front next to my hip bone). It feels like my intestines have a stick or rocksitting there in them so bending over or forward is extremely painful. feels like that is the other end where my food is stuck.
