Trying to figure it all out

I have been going through quite a bit lately, and there has been a lot of changes in my life. However, I'm right now at the point in my life where I'm trying to figure out why I seem to react a certain way in conversations with my mom and brother. Part of it is the fact that I'm still trying to adjust everything. I hate getting challenged (or more-or-less being told that my thinking/beliefs are inaccurate) and I tend to get a slight attitude. Essentially, I need an attitude adjustment. 

I'm slightly frustrated about the whole job situation. Yes, I'm completely trusting God, but the fact that the start of school is nearing, I think I'm internally stressing. I definitely bottle my emotions up, and I hate sharing how I'm feeling. However, this can be a detriment in some situations.

Also, even though I received my confirmation about "the situation," I'm fretting about the other end of it. The possible close to this is coming nearer, and I'm not sure what to expect.

I know that when I stress out about situations it comes through the form of how I react to my mother and brother in conversations. So, if I'm irked by something small my brother might say, I might overreact causing an argument in what could have been a peaceful situation if I just ignored it and gave it to God.

However, I realize that God says to "be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God; and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus" (Philippians 4:6-7). God actually says a lot about worry. To worry is to not trust God. It also puts my thinking in the wrong direction. Here are a few other verses that I'm learning to apply to my life:

• "Anxiety in the heart of man causes depression, but a good word makes it glad." Proverbs 12:25
• "Say to those who are fearful-hearted, 'Be strong, do not fear! Behold, your God will come with vengeance, with the recompense of God; He will come and save you.'" Isaiah 35:4
• "Therefore do not worry, saying, ‘What shall we eat?’ or ‘What shall we drink?’ or ‘What shall we wear?’ For after all these things the Gentiles seek. For your heavenly Father knows that you need all these things. But seek first the kingdom of God and His righteousness, and all these things shall be added to you. Therefore do not worry about tomorrow, for tomorrow will worry about its own things. Sufficient for the day is its own trouble." Matthew 6:25-34
• "Give all your worries and cares to God, for he cares about you." 1 Peter 5:7

I'm trying to seek God harder and harder because it puts my focus back on Him rather than the situations I'm currently facing. I'm trying my best to put all my cares on Him because ultimately He is my provider. Every outcome is a part of His perfect plan, and if I received a confirmation about how a situation will end up, I just need to trust God that He gave me this confirmation and that it WILL turn out that way.

Thanks for listening to me express what I'm thinking about. Sometimes I just need to get it out there in order to work through it. Talking it out can be a challenge because it always sounds better in my head. However, hammering it out on a keyboard really helps me to process through it.
