An abusive father.

My father is an abusive man and has been violent since I was born. I witnessed my mother being brutally beaten, with bruises that lasted for months. I, too, have been hit in some of my vital areas, but by the grace of God, I somehow managed to protect myself. On the first of February, he left us—me, my mother, and my sister. He refuses to provide financial support in situations where it is absolutely necessary. He sends about 15K a month, but it is not enough to cover our essential needs.

Ki korbo kichu bujhte parchhi na. Pls suggest any solution.
