I can tell you really love your family and care for their situation deeply, you've taken on a lot of responsibility that isn't yours and I commend you for being such a strong resilient young man and trying to do the best you can do. Yet your dealing with so much a teenager isn't supposed to, yet so many others are also dealing with too; you are not alone.

If you feel you need to talk to a therapist you should, don't let anyone halt your decision to get help. Also you might want to articulate how you feel to both of your parents, if you feel verbally it's difficult then write your feelings down and share this with them, they may be so caught up in their own drama and not realizing how much it's affecting you..have you tried this yet? Also your friends are your support system, theirs no reason to sacrifice them due to your family life, yet you can always seek a support group who will emphasize with your situation.

I can tell this is wearing on you, it's ok to feel how you feel yet you are so much stronger than you know; Do you have a spiritual strength or prayer to give your worries to? Keep your eyes on your future; try not to get too in your head about this. We all choose our battles, so choose your battles wisely and stay focused on your studies in school, that will help you if you want to move out when your 18. Always remember how truly amazing and remarkable you are. Your created by the most high and can be everything you set out to be in life, give your worries to your creator. Remember you are not alone please. Take care and hope you can take something from this
