Could this be cancer?!

Ok so I'm a 21 year old female. For the past 8 years I've had this bloated like pushin out feeling in my upper abdomen. This all started after I had severe panic attacks at 13 years old. I woke up after a month or so of panic with a swollen feelin upper abdomen. It's been that way ever since. It makes it hard to take a full breath most times. Sometimes I can get over it but it is usually more noticeable during times of stress and anxiety. My stools are usually normal except for when they are hard then bright red blood comes out. But when they are soft there is no blood. Since march though after some extreme stress I have been dizzy, nauseaous, and my lower back hurts with lots of rectal pressure. Like when I sit down to pee it feels like my rectum is pushing out for a bowel movement!! And standing I feel it and laying down I feel it. It is like my rectum is constantly moving I guess. Like it won't settle into it's normal feeling bc of all the pressure. My doc keeps saying hemroids and as for the dizziness she said I have inner ear fluid build up. I dont know what to do anymore help? Also my stools have been more loose lately but I think not is because of vitamins I have been taking.
