Stressing Headache...

I'm venting today, but not for or about anyone else but myself.  I'm angry with myself because for years, I had been trying to convince my mother to "get a life".  I wanted her to have friends other than the close circle of me and my son that she had; I wanted her to talk to people on the phone and get out to see them because I felt like her being stagnant would kill her, and now that she's gone, I'm realizing that I'm headed down that same path.  Although, I feel like I'm doing more simply because I haven't stopped doing what I love, but I have stopped doing other things that I use to do.  I haven't been to church, I stopped working out, I stopped hanging out with friends...now I have new friends, but the relationships are kept to texting and/or emails...I haven't even seen them.  I consume myself with my life's joy, which is my cake baking and decorating, but I haven't set aside time for me. I haven't had my nails done, never been to a spa or been to the movies or dinner by myself.  I'm in a relationship and although I believe I'm happy, the one thing that tends to stick out is the fact that I live co-dependently in that relationship simply because of my family environment was.  I'm a family person, and I'm use to doing things "together", my boyfriend is not because he didn't have the same type of family environment.  So when confronted with the "I should do things for and with myself" speech, I get angry, but he is right...I should do things for myself and by myself because I don't want to become stagnant in my life, but I fear that once I start, I will just keep going and where will that leave my relationship?
