Mental turbulence and losing interest.

I've suffering from emotional issues which is creating a lot of mental turbulence. One major cause is family thinking that I hardly care for them and I have nt been able to physically present at times due to my work. But whatever vacation I get I spend with my parents sacrificing my fun with friends so that they don't feel bad. Also next thing is related to my current relationship with my colleague. She is into lot of healing techniques and a mystical lady. That has attracted me . And though we are talking everyday. And she also has certain feelings, she doesn't wanna acknowledge them and her intuition says I m gonna give her pain and that will make her strong. Although she has feelings, she doesn't want to be in a relationship saying that we r just playing roles in each other's life. Once the role is over,nobody stays. And she becomes really unpredictable at times n I m clueless what exactly she wants..and I also have feelings for her.the only resort is my work, which keeps me away.
