I am so sorry, Sarai! I will most certainly be praying for you. I understand why you would want to suround yourself with like-minded people who will build you up.
I was brought up in a Christian family, so my Parents are both Christians - which is lovely. My little sister isn't a Christian though, and my older sister, although she is born again, we don't always see on the same page. I find it very hard with them sometimes, I often get pulled down by my younger sister who can't understand why I don't want to go out getting drunk and having 'fun' and I until recently I found it really hard to 'let go' of some of the things they were saying to me, and forgive them. But then I went to a meeting, and the speaker wasn't talking on the topic of forgiveness, but before the meeting started he said he had it laid on his heart to talk about bitterness, and forgiveness. He reminded us of how much God has to forgive us all the time for little things we do, but the thing that spoke to me most was how he said that being offended was a choice. Someone can choose to be offended, and so also one can choose not to be offended. It's easier to be offended sometimes, especially when someone's swearing at you, or mocking you for your beliefs, or etc. But it's just a choice. It's much harder to choose not to be offended than it is to be offended, but I've really been working on making the choice not to be offended when people purposely try to upset me, or mock me etc. In that meeting I let a lot of bitterness go that had been building up against my siblings - because I was finding it easy to get really upset at the way they were treating me. It was nice to let it all go, and now although it can be really hard sometimes, I make the choice not to be offended when they upset me. It doesn't always work, but by God's grace it has really been helping me.

In the end, all you can pray is that they will see God shine through you, in-spite of their mockery, and it will be a witness to them.
I have a beautiful homeschooling Mother as a friend, and sometimes I cry to her and tell her how alone I feel. It's such a horrible feeling, being lonely - not just being lonely but having people around you who just don't 'get' you, or mock you for being yourself. Thankfully I have my parents, but I still feel lonely at times, so it must be so much worse for you having no one there to chat to at home.
And don't worry about when you lose sight of Jesus for a moment and what He has done for you. The bible has so many promises, about Him never letting go of our hands, when we are faithless, He remains faithful. There are times in the scriptures when great men of God like Peter and David despaired - Paul even said once they despaired of life because of what was happening around them causing them trouble. If they despaired and lost site for a moment, you can be sure we will too.

Thank God we have an awesome God who is so understanding, full of grace and merciful.
Some scriptures that have really helped me:
Quote:
2Co 4:8-18 We are troubled on every side, yet not distressed; we are perplexed, but not in despair;
Persecuted, but not forsaken; cast down, but not destroyed;
Always bearing about in the body the dying of the Lord Jesus, that the life also of Jesus might be made manifest in our body.
For we which live are alway delivered unto death for Jesus' sake, that the life also of Jesus might be made manifest in our mortal flesh.
So then death worketh in us, but life in you.
We having the same spirit of faith, according as it is written, I believed, and therefore have I spoken; we also believe, and therefore speak;
Knowing that he which raised up the Lord Jesus shall raise up us also by Jesus, and shall present us with you.
For all things are for your sakes, that the abundant grace might through the thanksgiving of many redound to the glory of God.
For which cause we faint not; but though our outward man perish, yet the inward man is renewed day by day.
For our light affliction, which is but for a moment, worketh for us a far more exceeding and eternal weight of glory;
While we look not at the things which are seen, but at the things which are not seen: for the things which are seen are temporal; but the things which are not seen are eternal.
Quote:
John 1:12-13 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
Quote:
John 16:32-33 Behold, the hour cometh, yea, is now come, that ye shall be scattered, every man to his own, and shall leave me alone: and yet I am not alone, because the Father is with me.
These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world.
Quote:
Romans 8vs37-39 ...In all these things we are more than conquerors through him that loved us.
For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come,
Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.
Love you, sister! Cast your burdens on Him, because He cares for you. xxxx
