Lions_angel and jesusfreakgirl93, I must say, your posts truly spoke to me, how powerful they were...I know you didn't intend that but I thank God for prompting you to write those and for how He works in different ways!
Ok, so Life4Christ...it looks like the enemy is using someone close to you and someone in whom you have placed your trust in to dissuade you from what you know to be the truth. And actually, l would take it as a good thing in a warped way, cuz things like these tend to happen when we try to get closer and closer to God...the enemy tries to dissuade us with lies! This means that you are indeed doing the right thing in trying to further your spiritual walk.
Unfortunately, the devil uses whatever is close to our hearts to do that...friends, family, television, music...whatever affects us strongly, the devil tries to use to hurt us.
And I cannot agree more with what the others have posted. Just know in your mind and in your heart that the judging is not up to you, and that you must focus on you and God, not you, God, and what He does with other people...it's like when Jesus was talking to Peter about His other disciple John. Peter was inquiring about the way John would die, right after Jesus told Peter how he would die in glorifying God. Jesus basically told Peter that it wasn't his business how John would die (John 21:23), that Peter should not compare himself to other people, and that he should just focus on following Christ.
People are brought into this world in different ways, and that is God's discretion. Romans 11:33-35 (new living translation) says: "Oh, how great are God's riches and wisdom and knowledge! How impossible it is for us to understand His decisions and His ways! For who can know the Lord's thoughts? Who knows enough to give Him advice? And who has given Him so much that He needs to give it back?"
All that matters is that we take the route that we were given, and use it to seek God. It's really easy to have a pity party, trust me I know lol, but in the end, how do we deal with the life we have been given? And look at it as a powerful testimon that's to come out of your life.
As I write this, these passages speaks to me strongly, as I too am struggling with this curse of comparison (and most of the other things you too are struggling with), and it's so important that we have scripture in our hearts--I am learning this as I go along. If you have Scripture, then you have Truth, and then you'll be able to better discern what lies are and what truth is. You are surely not alone; seek the company of others who are in Christ.
Hope all my rambling helped! =]
