Your story is quite touching but right now I don't think bitcoin is the answer or solution to your current situation because Bitcoin investment is risky and anything can happen. Bitcoin is not a get rich quick scheme, it's a long term investment that takes time and requires patience. What you need right now is a job or skill that can be putting food on your table on daily basis. If after sometime you begin to receive a bigger salary from your job or earn good money from your skill, then you can now invest some part of it in Bitcoin.
