At Night I Get This Really Sharp Pain On My

At night I get this really sharp pain on my right side towards the bottom of the rib cage and I can hardly move, I am in agony and I struggle to get a pain killer. Sudden movement makes it worse and no sleeping position helps that pain ebb away. I do not drink alcohol, my diet is average and I've been having quite a lot of anxiety, stress and maybe a little bit of depression lately..
