Sorry to hear Legion - does not sound like a great life at the mo.
Generally I would pray for perfect protections - as much as necessary, possible, available and sensible.
Give the Divine (or Ultimate Good, as I call them) card blanche, as to the extend, amount and frequency of help you receive. Help to abolish suffering from your life! It might mean that armies of angels, or such, step in - that is fine. Love and joy always comes over suffering! It actually probably costs the Universe more energy to maintain suffering than natural love and happiness (- so no need to feel guilty about LOADS of help (where needed)).
Some healing processes can take time, so bear with them - you are NEVER forsaken (it is just this planet that can create the illusion that we are, but it is an illusion only)
Not to be clever - but if you have the money to pay for your father's bills - why not just leave and pay for your own place? Also research if you can get Goverment support, and or find charities that might provide help, safe house or similar. Safe houses are not necessarily just for physically abused people, but potentially emotionally abused ones as welll.
Love and Light - and praying your problems dissolve soon!!!
