It's reassuring to have others point out the poor behavioural choices of others. Validation and support are basic needs.
I hear you about struggling in job searching. Keep applying, keep trying. If you can keep mum, from the negative naysayers, to keep yourself from losing steam, even better.

Are you hopeful, to find both work and a home to support just yourself and your siblings? Are you familiar with any resources to help orphaned/abandoned children, especially when one sibling is an adult? I hope you can access resources that you need to become independent from these belittlers.
