I have irritable bowel syndrome.?

I’ve suffered with bloating,gas,constipation,diarhea, the feeling that I have to go BM again, even when I’ve just gone,and mucous in my poop. I hate going into public anymore because I need to make a few trips to the bathroom, most of the time I feel like I have to go, but then nothing. It’s embarrasing because my boyfriend picks on me. He alsmost hates going in public with me as much as I do. So my question is,,,would a good bowel cleansing help with the symptoms and what do I use. Is it safe to cleanse your bowels?
