Thank you all for the advice. It's very helpful and opening my eyes to a few things. He has talked about friends at school and tells me about his day. Everything seems to be going okay. He also wants to get involved in a club they have at school. He left the house today for a few hours to play with a new friend he made. So that made me really happy. Working on getting my GED is a good idea as well.. for myself and so my brother and I could spend a little more time together.
My parents aren't very involved at this point. My mom became very sick when she was pregnant with my younger brother, which was around the time she quit taking interest in my school work and the things I did. Once my younger brother was around 5, she started to get better but has been a different person since then. It's almost like she quit caring about me(I'm not saying she really did, she just acts that way.) Just one example: At 15, we were very 'poor' and my mom told me I wasn't allowed to eat any of the food in the house and I wasn't allowed to shower there. Thankfully, a good family friend took me in and got me out of that situation. My mom has apologized since then for her behavior and we've gotten past that. She quit helping my brother with school work a few years ago and won't take him to join any of the activities he wants to be involved in. I've pointed it out that he is her child and I shouldn't have to be doing her job, but nothing has changed. So I really want to be there to help him as much as I can. Also, another reason why he may be so sensitive is because when my mom gets mad.. she'll call him names. She apologizes after, but its still not right. And I can tell it hurts his feelings.
My dad works a minimum of 72 hours a week, so he's not home much. But on the weekends he'll take my brother out so they can spend time together.
I'm trying really hard to make things better for my brother, but it's just stressful and there is only so much I can do. :/
Yes, there IS only so much you can do. You are being an awesome big sister but keep in that in mind. Help him as much as you can but don't feel guilty, you are not his mother nor should you be expected to fill that roll. I second getting your GED, you are doing great girl!
