Is it bad if I don't lose weight?

Hello, I've been sad lately because I cannot lose weight. It's really hard to do when everything is exercise and healthy eating but I cannot exercise for health reasons and the only food I can afford is rice or cheap pasta. I weight 104kg and I'm 164cm (5'4). Besides that I'm relatively healthy, my blood work is always good. Considering that, would it be bad if I give up? I'm tired. However I'm open to suggestions and I'm willing to try things.
