HELP

This is a cry for help.I will start from the beginning so i hope someone will understand us and help us (im sorry for my bad level of english) ...Hi all my name is Krasimir half bulgarian , half russian 28 years old.I never knew that this will happen to me/us (my family)but in the life there are ups and downs.In our case is very serious down.I live in Spain with my father and mother.18 Years ago my father came here in Spain alone without knowing any spanish and leaving me and my mother back in Bulgaria to work and study.He came here without having someone to stay to or someone to help him. He came with 150 deutschmark which is something like 76-77€ in his pocket and suitcase with clothes.Some scamer job company lied to him that he will work at the field here gathering fruits if he pays them some amount of money etc...He got scammed.He was lied and broke without money living on the streets for about half year.He was opening doors at the supermarkets,helping with parking cars at the street.We send him accordion ( not only one but few, the others were broken) because he knew how to play music.So he become a street artyst for about year or two.He got rental apartment with another guy from Bulgaria ( still one of his best friends).He get higherd at construction companies, after that he worked many year like security.He maneged to buy new car ,apartmen and finaly me and my mom came to live here in Spain with him.I started working with him in that security company.After few years we got fired from our bad boss for wrong accusations.Good lawyer helped us to sue him.With the money that we got and some savings we made my father´s dream come true.We opened food store here in Spain.Store with rare foods from Bulgaria,Russia,Poland,Ukraine,Romania,Moldavia and few other countries.We have our store working from 10 years.We work everyday of the year from 08:30 till 23:00, never close to rest.Its fun job where i meet clients from many countries here in Spain and also showing our products to them.Few months ago we had to give back money to a friend who helped us when we started our business.My father always helped people, we never lied to someone to profit or benefit or something else.But few months ago two families from our country who are living on the streets here in Spain like my father back in the days came to us for help.They wanted to save their money to us because they cant make bank accounts because they are homeless.And when they nned their money we were going to give them back.He knew them, not bad people (but that was not the case,we were wrong).Almost every day they were bringing small amounts of money and we were taking notes with their signs so there will not be any mistake.For half year they storaged about 14k-15k €. And everything was fine till one month ago when they suddenly told us they want all their money back to go back to Bulgaria.Before when we were talking about the ground rules of our deal they told him that they will come for their money after year 2020 so we can use those money for business till they come ( i was against that deal, i didn´t belive those people but my father didn´t listen to me, he thought they were honest people ) ...so it was big bad surprise for us when they come for them .We dont have those money yet, we have heavy bills to pay, months May,June,July,August are prety bad and weak months for business like our and now that...We had to go to our banks to ask for a bank loan.Bad news... neither one of our two banks accepted our need for help.So now we must sell our store - the work of our life...My father and my mother are heartbroken, we dont know what to do,nobody from our friends can help us, there is no another way unless if a miracle happens.We pray and we dont know what else to do .This is our last chance or we go down and start from zero.Please people help us with any amount till the end of July 2019, please save us.This is our last hope.Please help us !
