You may improve your life temporarily but it will all come crashing down one day when the immigration authorities catch up to you. You will be deported and banned from re-entering the US. There are many developed countries where someone with your skills can obtain a temporary work visa easily. You can live and work freely and legally, get on your feet financially and maybe attend university there to help you get into the US legally in the future.
Maybe it will help if you tell us where your citizenship is and we can help you with suggestions of other developed countries that will allow you to come for a 1-2 year temporary work visa.
