Struggling with GI Issues and Medical Gaslighting

I’m not sure if this is going to make any sense but I’ve been having gi issues almost a year now but lately because of how bad my pain is it’s like I don’t have the strength or muscles to have a natural bowel movement even with taking linzee daily even when I take my suppository to help me have a bowel movement it’s very little and takes alot of energy even with so little coming out and it’s practically as liquidy as water but burns like acid. I was supposed to have a upper and lower scope but my surgeon wants to wait till after I see the cardiologist because I’ve been having silent heart attacks for three years but it was just discovered a couple days ago when a doctor asked if I was told if a doctor had told me I had a heart attack and of course they didn’t doctors where I live unfortunately suck I only have one doctor that tries to help my pain and illness. So many doctors over the years have legit called me crazy and pretty much gaslighting me into thinking I’m not in pain at all and I start feeling like I really am just insane but this has been going on for almost a year even when I had cut out the major stressors in my thinking stress has been making me so sick. The level of pain alone stresses me out and when it gets really bad the pain makes me puke and I swear that the intensity of the pain triggers me to get sick. A doctor has told me I could have what they called cycling vomiting syndrome but unfortunately I can’t get the scopes to see if I do until my heart issues get better
