For the past 4 days I suspect my IBS has come back. I haven't had it for years

I'm trying to pinpoint what is flaring it up. It is the kind that is worst in the morning and I need to go toilet which makes it feel better for about a minute and then I need to go again and get more pain/hot sweats

It is so painful.
The only thing I can think of diet wise that has changed is Easter chocolate. I was rarely eating chocolate anymore and when, literally just a row and the last few days I've had more, yesterday I had about half an egg and this morning I would say was the worst day so far. The other food is red grapes.
Other than that, it could be stress but stress from what? The only thing I can think of is there are lots of things going on with mum, frank and my nan and it might be subconscious.
Sorry to post this but I needed to get it out as I feel so misunderstood. Harro doesn't seem to understand how painful it is or believe that chocolate or other foods could trigger it
