I'm going to try to keep this short, my entire family is a treasure trove of mental illness, abuse and neglect.  As the headline reads, I really only have one strong relationship with my sister. We had strong bond when I was very young, but she left home abruptly due to the environment at home. Over the next couple years we would see each other a few times, but then there was no contact for about 10 years.  When she contacted us again, I was a teenager by that time,  and  my shit little world suddenly had something worth a damn in it. Fast forward many many years later, we've been through a lot of emotional and stressful ups  and downs, and we've always been there for each other. She cried when I told her about my bipolar diagnosis as she was diagnosed during the time we had not contact. We live in different states, but I've been planning on moving for some time now, and that will happen in about a year. I've been looking forward to it for a very long time, it's probably the only thing that keeps me going. So with that bit of back story over, a year or so ago, her son gets married. And now everything is about the daughter in law. I'm not that selfish to think I have to monopolize her time (I understand the importance of the relationship). But suddenly, I wont hear from her for weeks, have to almost beg for video chats. When I do hear from her, I hear about all the video chatting with the daughter in law, all the stuff they plan to do. Which is all the stuff we planned to do when we both retired. I mean, it's almost all she talks about. I'm really struggling with thinking I'm being selfish for having these feelings vs. Just feeling like I'm disappearing. Sometimes I actually feel like I'm fading away, and being replaced. Like I could actually not exist (not suicidal) and I don't think she would notice for a while. I'm always wary about sharing, but I recently lost my therapist, just needed to get this out there. Part of me knows I'm being unreasonable, I do have moments of rationality. The rest of me is just wallowing in this pit of despair.
