"Those who sow with tears will reap with songs of joy." (Psalm 126:5)
I know it doesn't seem like it now, but I think that one day you'll look back at the momentary sufferring you're experiencing and realize that it was one of the best things that happened to you. That sounds crazy, but I can speak from experience on this. I went through a period of severe loneliness, depression, and isolation, to the point where I began flirting with the notion of suicide. Well, if I hadn't hit that "rock bottom", I doubt I would have sought after Christ otherwise. Sometimes, God has to allow our hearts to be broken so that they are easier for Him to mold.
So remember, you are not alone or unique in your current struggles. I've read stories about Muslim converts who, upon telling their families about their decision to follow Christ, they are essentially exiled and viewed as an "embarassment" to the family, they are no longer treated as sons or daughters. Sometimes, this is inevitable. What we have to ask ourselves: is it worth it? That's for you to decide.
Keep in mind that you have already been adopted into a much larger family than the one you left behind. Jesus said it well in Matthew 12:
46 While Jesus was still talking to the crowd, his mother and brothers stood outside, wanting to speak to him. 47 Someone told him, Your mother and brothers are standing outside, wanting to speak to you.
48 He replied to him, Who is my mother, and who are my brothers? 49 Pointing to his disciples, he said, Here are my mother and my brothers. 50 For whoever does the will of my Father in heaven is my brother and sister and mother.
My thoughts and prayers go with you brother
