I totally get where you are coming from. I am a single parent and there are times when the loneliness does get to me. The church can at times foster that feeling when you see all the 'happy' families. There have been times when i too just long for a hug and so i try to reach out to others by extending fellowship. It is not easy and time heals all wound but before you get to that place where you feel you have totally 'moved on' take courage in the fact that God has promised that he will never leave us nor forsake us. We are never really alone for God is there even when we can't seem to feel His presence.
There are things about my life that i do not understand but i know this, God is good and kind and i thank Him that nothing happens in my life that is a surprise to Him He has a greater plan than my small vision can imagine.
God loves you no matter what and He is ever present.
God bless
