Poor Bella! I'm so sorry to hear about her diagnosis. Unfortunately, it's true that mediastinal lymphoma with fluid in the chest generally has a very poor prognosis in cats. You could certainly request referral to a veterinary oncologist for a consultation about this - the oncologist could give you a much better idea of whether there are any treatment options at all that might help her. If you aren't able to pursue referral to a specialist, then I'm afraid it's very unlikely that there is much at all that can be done by your family veterinarian - this is quite a serious problem that generally does not respond well to treatment. There may be some things that could help to keep Bella comfortable for a short time, such as draining the fluid to help her breathing and starting her on a steroid such as prednisone, but it's unlikely that these things will help for long. Again, I'm very sorry for the bad news you've received - cancer is a terrible disease, in pets just as in people. :(
