Thank you so much everyone. This advice is really helpful. There are a few things I want to mention that would probably help you see a wider scope.

First and foremost: Just recently, she injured her knee and tore her ACL and everyone has been chipping in to help to take care of her daughters, including myself. I had plans to go abroad this year but had to put that on hold because she needs someone to help take care of her daughters and trusts me with them the most (not saying no one else can watch them - I just know the kids' schedules, mannerisms, etc). I was bummed at first, seeing that teaching abroad was one of my goals to jump start my teaching career but I am seeking out other opportunities. She will be healed by next February so the situation is only temporary.

I moved in the summer before my senior year of college in 2011. At first, she'd asked me if I wanted to find my own place or live with her to save money. I honestly didn't think I'd be living here this long and every time I bring it up or want to address moving out, she mentions my financial situation and 'being grateful for the help' so I can be debt free soon. She has asked me before if I am happy living with the family and I wasn't completely honest, partly because I didn't want to admit the truth and I didn't have any money to move out. I suppose I've gotten comfortable with living here.

I am very grateful for all she's done: taking me on family vacations, providing food and shelter, including me in everything, always putting everyone else before herself. She is not a negative person, she has a kind heart and gives more than she should but the things that bother me the most are:

- constant frustration (it seems she doesn't know how to manage stress)
- never knowing if I am doing something correctly - especially when it comes to things I ought to know by now ("ADULT" decisions). she needs things done perfectly or she just does it on her own
- comparing my life to hers. she is always telling me that I have an easy life because I don't have to deal with difficult family matters (money, bickering) or that I am lucky because I have minimal bills.
- high-strung or impatient

Maybe I'm over-thinking a lot of things because she's my sister and I need to build 'thicker' skin but really, I feel like a kid sometimes. I enjoy spending time with my nieces and they always tell me that they'd be very sad if 'Auntie' moved out. Maybe I am limiting myself because I am scared I won't be able to make it on my own since my job doesn't pay much but I feel I need my personal freedom.
