My intestines feel humongous

[ifeelcrazy]

Let me preface this by saying I got diagnosed with anxiety disorder back in October.  My mom and sister have both went through bad anxiety problems as well.... averaging 6-12 months.  My anxiety is very much triggered by unusual symptoms in my body.  My latest trigger is my stomach.

About 2 weeks ago, I woke up with a really bloated stomach.  Except it wasn't my stomach in general, it felt like it was my colon.  It was on the right side and was mildly uncomfortable.  No pain.  Just bloated to the point where I was uncomfortable when I sat a certain way.  I waited 5 days and went to my GP on Tuesday afternoon.  She told me that it could be one of 3 things- ovaries, appendicitis (which she highly doubted because she did a pelvic exam and I was in no pain), or constipation.  My temperature was normal, bp was normal, and the urine test was clear.  I got sent directly to get a transvaginal ultrasound which showed everything was normal.  The doctor told me to just take miralax.  Which made no sense to me because I didn't feel like I was "irregular"... I go at least once every day. 

So then Friday afternoon, I went and bought some colon cleanser.  I was on that for about 2 days but felt absolutely sick- headache, bad stomachache, extremely tired- so I stopped taking it.   

Fast forward to a week later, it is still not gone.  My colon (or whatever is in that lower right area) is still very bloated, especially in the morning (but continues to be so all day usually).  I am still uncomfortable.  Really uncomfortable.

I talked to my mom and she told me that IBS runs in our family and that was all it probably was.  I know my family is getting sick of hearing me complain but I am really worried that it is something bad?! 

Any insight would be MUCH MUCH appreciated.
