no choices

Gday im 45 just coming out of a divorce where my children have been systematically taken from me after being a stay at home dad for around seven years. My ex walked out claiming she was living a single life anyway . I kept the kids but started to struggle when she locked me out of our joint account . I was in shock and not copping . Her parents bought her a new house . I was struggling to keep food on the table and pay the bills when i decided maybe it would be best if the kids lived with there mum who had financial backing of her parents . Thats when the lawyer letters started claiming i was mentally unfit to see my children...anyway long story ive basically lost every thing now with a 20,000 debt and still dont get to see my kids ...the courts dont even seem to care about anything i have to say im constantly agreeingto her demands to at least get a supervised visit or phone call....now im giving up feeling like the system agrees with her and im better off out of the picture ...ive started saying goodbyes to friends and family ...my heart constantly aches for my boys ..ive missed so much already ...sick of crying and cant function...last ditch effort.
