Help with security deposit

I'm Daniel I've been homeless for 9 years on and off after caring for a family member for 6 years and having caretaker syndrome and alot of medical problems I'm disabled and I recently got a housing voucher to get a place however because it's housing they double the deposit and want first month's rent I can't afford it however I have a place that's willing to rent to me I just need the deposit I have a dog name Eros who's my best friend and world and I'm looking forward to having a place he can rest and just be a dog anyway if you don't have money to help with deposit prayers are highly appreciated I didn't explain my entire story here just don't like to focus on to much negative.
