We understand that you are feeling depressed, lonely, and sad, and that you are seeking God's help in securing a matrimony. First, we want to remind you that God cares deeply for you and wants to give you a future and a hope. It is important to remember marriage should be between a man and a woman and if she is not a Christian it is not equally yoked. Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? And what communion hath light with darkness? (2 Corinthians 6:14) Also, you should not worry. Trust in the Lord with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight. (Proverbs 3:5-6)
However, we want to encourage you to find your completeness in Jesus Christ alone. Only then can a spouse complement the wholeness we have in Jesus Christ. The Bible tells us, "Delight yourself also in Yahweh, and he will give you the desires of your heart." (Psalm 37:4 WEB)
You mentioned feeling depressed, lonely, and sad. We want to remind you that God is your comforter and the lifter of your head and face. Seek him in your loneliness, and know that he is always with you. Safety is to be found in the multitude of advisers. (Proverbs 11:14) Therefore, we recommend seeking wise Christian counseling to deal with these feelings.
Regarding your desire for matrimony, we encourage you to trust in God's timing and to seek his will above your own. We pray for you and her family. We pray that if it is God's will, that her and her family would grow to like and love you, but we want to remind you that God's will is always best, and his ways are higher than our ways.
"'For my thoughts are not your thoughts, neither are your ways my ways,' says Yahweh. 'For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts.''' (Isaiah 55:8-9)
We also want to remind you that it is only in the name of Jesus that we can approach God the Father. It is only by the name of Jesus that we can be saved.
"He said to them, 'But who do you say that I am?' Simon Peter answered, 'You are the Christ, the Son of the living God.'" (Matthew 16:15-16)
We pray: Heavenly Father, we lift up our brother to you in the mighty name of Jesus. We pray for your comfort and peace in his life. We ask that you guide him in your will for his life, and that you give him a future and a hope. We pray for your will to be done in his desire for matrimony, and we ask that you give him patience and trust in your timing. We pray this in the powerful name of Jesus Christ, Amen.
