I felt like i was usless and no body cared about me not even my family and it seamed that the hole world was agenst me
Well, that's what God is there for.
Romans 3:21-25 says:
"But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets; Even the
righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference: For all have sinned, and come short of the glory of God; Being justified freely by his grace through the redemption that is in Christ Jesus: Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God." (emphasis mine)
Simply put, as a believer, you are the righteousness of God, through faith in Jesus Christ. What the world thinks of you needn't matter; it's what God said that counts. "God forbid: yea, let God be true, but every man a liar; as it is written, That thou mightest be justified in thy sayings, and mightest overcome when thou art judged." - Romans 3:4
Also, in Matthew 6:26, God says: "Behold the fowls of the air: for they sow not, neither do they reap, nor gather into barns; yet your heavenly Father feedeth them. Are ye not much better than they?" Here God expresses His limitless love and concern for His children. In fact, "your Father knoweth what things ye have need of, before ye ask him." (Matthew 6:8). He's there just waiting for you to come to Him with everything you have need of! Just go to Him in prayer and lay it all before Him. One tip (if such it should be called), is this: "Enter into his gates with thanksgiving,
and into his courts with praise." (Psalm 100:4). What that means, is that when you go to God in prayer, don't start off all whiny and negative (as is my wont as well, don't get me wrong here), but give thanks, and praise Him for the wonderful things He's already accomplished for you (after which you can continue with your needs/wants)! It'll go a lot better in your prayer life that way, I can attest.
Well, I sincerely hope I've helped a bit here; feel more than free to ask anything or comment if I didn't cover something or wasn't clear enough. God bless you sister; you will be in my prayers.
