I feel so angry I just might cry!

So I'm 27, I have a masters degree in music, a full time job and I'm living with my parents. My financial situation is Okay and my friend wants to move into a place with me. I was excited about this. For the last year and a half I have been contributing to groceries and utilities. My dad had been underemployed or out of work altogether for about 9 months and just recently got a full time job with better pay. My mom is mentally ill and is on SSDI.

When I gently told them that my friend wanted to move out of his current living situation and move in with me in an apartment she responded with "We'll see." As if I needed her permission. She reminded me that they rely on me for my contribution and that there will be other bills that I said that I would pay come March. I assured her that those bills that I said I would help with I would still help with but that once I move out groceries and utilities would go down because I wasn't' using them.

I feel so used. I know that they love me but I just feel like they want me to make life easier on them. Meanwhile I'm getting more depressed and anxious, life seems worthless and I think that because I'm living with my parents I'm not worth anything. It wasn't so long ago that I looked down on people like me, 27 and living with their parents, going to meaningless jobs and not doing anything with their life.

I've become my own worst nightmare. *sob* I hate this. I don't like being so angry and hurt all the time.

I'm sorry. I just needed to vent. I'm going to move out whether they like it or or not.
