Should I take this drastic step to gain financial freedom?

It seems that you are in a really difficult place at the moment. But before you go down this avenue - dont forget there are other avenues of help - such as hostles for abused women - Refuge - www.refuge.co.uk might be able to help or there will be local refuges in your area that will give you somewhere to stay and help you find a job etc. Which ever path you choose I wish you luck, health and happiness
