Hope I can help
I know this post was quite a while ago, and I don't know how you're doing now, but I really felt moved to try and help.
I'm not an expert, but as a Christian, all I feel I can say is this. Jesus said "I am come that they might have life, and that they might have it more abundantly." - John 10:10. It is not God's will that anyone should be depressed, or lonely, or experience anything bad. God doesn't want anyone to be miserable. But according to the Bible, the problem that I have, and that you have, and that everyone else has is "sin". Sin is falling short of God's glory. Everyone has sinned; we all do wrong, "For all have sinned, and come short of the glory of God" - Romans 3:23.
Sin is what separates us from God. It will send us to the lake of fire for eternity. This is not what God wants. He wants everyone to be saved from sin and its punishment. That's why Jesus Christ died on the cross: to pay the punishment of our sin. Because Jesus is God (God is a "trinity", one God, three persons, Father, Son, and Holy Spirit) he has no sin, so he could sacrifice himself in our place. He shed his blood, died, was buried, and on the third day rose from the dead: "For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures" - 1 Corinthians 15:3-4. God promises that everyone who asks Jesus to save them from their sin and its punishment will be saved and forgiven forever: "For whosoever shall call upon the name of the Lord shall be saved." - Romans 10:13.
I know many people don't believe or appreciate what I just told you, but I believe it with all my heart. Jesus saved me, and others I know, so I had to try and point you to him. If I may offer, I recommend reading the Gospel of John, and praying for God to show you the Way, which is the Lord Jesus Christ.
God cares about you, and so do I, His unworthy servant. I'm open to questions if you'd like. God bless!
