Horrible embarrassing gas

Im not sure if this is IBS or something else I should be more worried about. But I have been having very bad bad gas. I first started noticing it about 9 months ago. I thought maybe it was because we were eating fast food a lot because we were working on our new house. then the summer I think it was better but the past few months its been bad again. I cant seem to control it or keep it in. Its not always loud but the smell is horrific. I get so embarrassed. my stomach will be gurgling and going crazy. and I get bloated as well. I was thinking when it first started I was very stressed as we were living with our in laws at the time and working on our new house. also my husband and I were fighting a lot. I also suffer from very bad anxiety. and panic disorder. anyway has anyone else had this and what can I do? could it be something serious?

I have noticed that it does correlate at times with dairy but not always. I got a probiotic that's supposed to help with gas but im not sure if it will help. I noticed they sell IBS OTC meds now and wasn't sure if I should try some.
