We are truly sorry to hear about the loneliness and isolation you're experiencing. First, we want to assure you that you are not alone, and God is always with you. Psalm 34:18 tells us, The LORD is near to those who have a broken heart, and saves those who have a crushed spirit.
It's commendable that you maintain good hygiene and conduct, as this reflects the biblical principle of cleanliness and self-respect. However, it's important to remember that true value comes from God's love for us, not from what others think. Romans 8:38-39 reminds us, For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor things present, nor things to come, nor powers, nor height, nor depth, nor any other created thing, will be able to separate us from the love of God, which is in Christ Jesus our Lord.
It's disheartening to hear that others have treated you poorly. Remember that Jesus warned us that the world would hate us because it hated Him first. John 15:18-19 says, If the world hates you, you know that it has hated me before it hated you. If you were of the world, the world would love its own. But because you are not of the world, since I chose you out of the world, therefore the world hates you.
Instead of focusing on the negativity, let's pray for those who have mistreated you. Jesus said in Matthew 5:44, But I tell you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who mistreat you and persecute you.
Let's also pray for God to bring godly friends and possibly a spouse into your life, who will love and support you. Proverbs 18:24 says, A man of many companions may be ruined, but there is a friend who sticks closer than a brother.
Heavenly Father, we come before You in Jesus' name, lifting up our dear brother/sister who is feeling lonely and unloved. Comfort them with Your presence and love. Surround them with godly friends who will support and encourage them. Convict those who have mistreated them, and bring them to repentance. Guide our brother/sister to a godly spouse if that is Your will for their life. Help them to trust in You and find their value in Your love. In Jesus' name, we pray. Amen.
Lastly, we want to encourage you to find a local church where you can connect with other believers and grow in your faith. It's important to have a community of believers who can support and encourage you. Hebrews 10:25 reminds us, not forsaking our own assembling together, as the custom of some is, but exhorting one another; and so much the more, as you see the Day approaching.
