Hi. It is good that you can share your feelings. Something that you will grow to appreciate is that a person is more than his or her feelings. Prayer is never bad, but you can pray while taking action. I suggest, in this instance, that you not just meditate on your gross feelings; rather, praise God and move to some uplifting music (even if it is just tapping your fingers with the songs).
It is important to lay your burden down before God, but once that is done-- get up. King David did this after a horrible experience. Even though God did not grant his request (his firstborn died), David chose to get off of the ground and eat some food. In other words, he eventually understood that "it" (the horrible situation) was in God's hands. He chose to trust God and go on living life.
God alone knows your pain, frustration, wrongs and where you have been wronged. He knows the seemingly insignificant moments in your day, and He knows the BIG problems or praises on your mind. God loves you, even when you do not feel that good feeling of being loved in the best way. He loves you, through and though. He loves your too-busy youth leaders, aggravating mother, and uncaring brothers, and misunderstanding friends, too. Therefore, God is the right one to keep seeking. BUT, do not be idle in your seeking.
Find an activity that will signify your love for God that is safe and not waking anyone up and do that activity.
Write; sing/make music/listen to music that helps you relax in the Lord; stretch/exercise; step away from the electronic devices; create a game from art supplies in your room (challenge: base it off of Galatians 5)----- those are just some ideas.
Oh, and, of course, read the Word, listen to it, read it to yourself in front of the bathroom mirror, thinking on how it might apply in your life. (A good scripture for this is: "The Lord made me...")
Pray for those with whom you have issue. Ask God to bless them. It will do something in your heart... eventually.
To God be the glory.
(my ideas are not to be answers in themselves, only a motivation for you to find the best fit for your current need.)
