If we have faith in God, then He will help and take care of our needs.

Faith is more than just a belief. It is the actions that we do and the choices we make because of a belief. Because of something that we know. Sometimes it's hard to make a choice that will cause a temporal hurt. Like choosing to find and make new friends because the ones you currently have are going down a path that is different than what you want.
In 1 Kings 17 Elijah, the prophet of the Lord, asks a widow with only enough meal and flour for one person to make him a cake. She believes that he is a prophet of the Lord, however this is the last of her food and she wants to give it to her son. But she has faith in the Lord. Because of her faith, the Lord supplies her with meal and flour until the there is food again in the land.
I know that if we have faith in the Lord, then He will help us and take care of our needs. Sometimes it may not be when or how we want, but He looks out for us. Our Heavenly Father loves us more than we know and by following him and doing our best we can also reciprocate our love for Him.
