I am currently relying on food and water from Haram income sources due to family circumstances, and I have little control over it. As a student without job options, how should I address this issue with my parents without causing negative repercussions?
You should not think that the income of your family is Haraam before having definite and clear evidence.
If you don't have a definite evidence that it is from Haraam source, you will permissible to utilise it. If you have a definite clear evidence that all the income is from Haraam source, then you have to avoid Haraam as much as you can.
