I am a single parent. Me and my 14 yr old son are living separately. He is living alone in a studio type old apartment in Town and Country Homes in Binan Laguna. I can not stay there because I am getting allergies due to mold or insects bites. I really love to stay with my son but I can not. I am working in Ortigas and currently staying in a boarding house. I have a 75 sqm land in Laguna where I want to build a house for my son then I will go there very week so we can spend time together. My salary is not enough to build a house in Laguna. I have sidelines but I am paying my maintenance medicines and paying insurances. I am paying the land mortgage as well and I spent my savings due to my health issues. I had total thyroidectomy and the side effect is weak immune system. I need to build a house for my son so in case something happens to me he will not live in the streets. I do not have parents anymore while my siblings are working in the Middle East earning below average salary and they have their own kids too.

I also want to help other people who is looking for a place where they can stay for free , a night or more. I will join the couchsurfing so people can stay in my house without payment. I will also post it in facebook.

Thank you in advance. God bless you all.
