I Care About Homeless People

I found out my coworker was homeless. She'd been staying with a friend but that friend can no longer support her and now she has to go to a shelter. Me and my roommate's apartment can't fit another person in and even if we let her stay, she wouldn't have space or privacy for herself and I think that'd make her very stressed and uncomfortable.

Or am I wrong and I'm just overthinking things? Any ideas on how I can help?
