:welcome: to the forum!
I'm so sorry to know about your struggles! May Allah ease your hardships and guide you to a way out, Ameen! You mentioned being a nanny in your list...I've seen some local help wanted ads looking for nannies or caretaker for elders. Check them out! At least in the States we have such a thing as wanted ads.
As much as you feel worried about the negatives that are going on, be thankful for the positives! Here's a thread I read that made me realize we tend to let our minds worry about the dark things: The Black Dot.
So 3 things I noticed that are an asset to you:
1. You are able to communicate in English
2. You do know how to navigate the net and use a computer
3. You're hopeful, even though you may not feel it yet!
Places to look for employment: library, school cafeteria, grocery store, mall, a walmart, bakery, factory, home depot. At least a part time job will give you steady income. A full time may help you find a more permanent type of home. Think of sub-leasing an apartment, or even rooming with strangers (with standards of course! like non-smoking, non drinking, no pets, etc). Don't be afraid to move to another state! All of earth is Allah's land and where ever you're meant to find success will be!
Think outside the box!
