Hi Mandy
Nice to meet you and welcome to Psych Central.
I have to tell you I've been in therapy for around 15yrs (I'm 34) and I've been a member at this site starting in feb. of this year.
I can't tell you how much the people here have helped me so much in so many ways.
I have a long way to go and I'm just beginning to open up more.
I hope you can get the help you need.
I can understand what your going through a little bit because my best girlfriend growing up went through exactly what your describing.
I was very close with both sisters and would watch this relationship. It was very sad and very dysfunctional. It caused a lot of pain for my friend the youngest one.
I hope that you get some real help and benefit from therapy and meet some friends and get some support here.
Good Luck
Take care
Eva
