I have read so many posts on different board where Christians say this.
There are many reasons people are as they are. Some are naturally loner types, while others
are outgoing. Some are selfish while others are giving.
A pastor once said don't worry about finding the 'right' person. Concentrate on being the 'right' person - Spiritually. We are preparing to be with our Lord and we should prepare self accordingly. I know this is not what you want to hear, and is not entirely what you want, but there is wisdom in what he said.
When we get where we need to be in Christ, He gives us our needs - as He sees them, and even the desires of our heart.
Psalm 37
4 (H)Delight yourself in the LORD;
And He will (I)give you the desires of your heart.
5 (J)Commit your way to the LORD,
Trust also in Him, and He will do it.

Some of us do not come across well in social situations, so a suggestion here, if this is your problem. Do some volunteer work. Working with people helps us make our self more readily
to others.
Loneliness is not a problem with just singles. It is often in married couples as well. I used to feel lonely all the time. Once I agreed with God that Jesus is my Savior and was indwelt with the Holy Spirit I never feel alone any more. I realize this is not the same as being lonely, as my husband was in the Military for many years and was deployed often. Not having him in the house with me made it seem rather empty, so I spent time with the kids at their home often.
This is a great lesson in the fact that things do not satisfy our needs. Often we strive for things and become collectors, but those come in as poor seconds compared to people. I do believe this is why the great commandment is to love.
I pray that whatever God sees as your current need be met in accordance with His grace, mercy and comfort to you, for Christ's sake.
