Have you experimented with different fruits and veggies, and eating them together with other foods, etc? My IBS gets very aggrevated if I have e.g. apples, grapes, pears, plums, and several other fruits, especially on their own, and raw carrots is a complete no-go (sadly, as it's one of my favourite snacks!). However, I find that I'm ok with mango, banana, and papaya, especially if eaten together with something else, like plain yoghurt. Veggies I can handle if they are cooked, and especially when eaten together with lentils or quinoa (I've cut out grains as I feel better without them), and some plain yoghurt.
I really feel for you, it sucks to not be able to just grab a piece of fruit as a snack, but as you know it's all trial and error with IBS and reactions are very individual, so just keep trying different combinations of things.
Also, for a while when I was going through a particularly bad phase and felt forced to cut out fresh fruit completely, I started baking fruit slices (without added sugar), so I'd get some fruit that way. Buckwheat flour is great for grain or gluten free baking and you can add any fruits/berries you want.
Re juicing, you won't know until you try, so why not give it a go. I can't really have fruit juices personally, but sometimes I blend banana and blueberries into a smoothie with some yoghurt and that works really well for me.
I also have IBS, i know how you feel.
Having it with something else might help, the only thing i can eat is boiled apples, maybe try cooking it, some vegetables trigger my ibs some are ok
