Save our home

My husband and I have rented the same house for 25 years. Over the years our rent has gone up, while our income has decreased. We pay as much as we can each month and up until now our landlord has been supportive. Over the past 5 years our rent has continued to fall behind. Though he promised to work with us and never evict us, he lied. We are now looking at moving out of here in 3 weeks! This is impossible for us and with a couple of more months we can move. Paul is 78 and not able to do as much as before. Neither of us are able to work. I am sewing for extra income, but it just isn't enough. If we can raise enough to give us some extra time, then we can get ourselves out of this position. 
This is really hard for us as we are not used to having to ask for help! Please help us get through this crisis!
