We are truly saddened to hear about the burden you've carried due to the words spoken over your life. We believe that the power of life and death is in the tongue. First, let's address the issue of curses. According to WEB, Christ has redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one who hangs on a tree. (Galatians 3:13)Yes, curses are real, but because of what Jesus did on the cross, we have been redeemed from all curses, but we must appropriate this for ourselves.
But know this first of all, that no prophecy of Scripture is of any private interpretation. For no prophecy ever came by the will of man: but holy men of God spoke, being moved by the Holy Spirit. The same applies to curses. Words spoken, especially by a parent or family member, however, have a huge impact on our lives because we give them a place of honor. Furthermore, a father should be a source of blessing rather than cursing. (Ephesians 6:2-3)
Moreover, we see the majority of your issue is rejection from your father and romantic rejection. Humans were created for love and acceptance. However, many times our earthly parents fail us, and others in life might reject us. Yet, our true value, acceptance, love, and approval come from our Heavenly Father. He loves and accepts us unconditionally. Even more, He says in (Psalms 27:10): Though my father and my mother have forsaken me, then Yahweh will take me up. God wants you to turn to him for acceptance and not the world or your earthly family.
