Hello Meeshell: This appears to be your first post here on PC. So... welcome to PsychCentral… from the Skeezyks! I hope you find the time you spend here to be of benefit.

With regard to your post, I'm afraid I'm probably not the best member, here on PC, to be offering advice with regard to the situation you describe. I was an only child who grew up, many years ago, in a quite elderly extended family. Among the relatives I grew up with, the next youngest member to me was my mother. And she was older when I came along! I spent a good share of my childhood going to one funeral after another as they all died off. Consequently, I don't have a lot of experience with family issues. Now it's just my wife & I.

A number of years ago, I participated in a partial hospital program. And one thing they told us was: "Don't should on yourself." You feel as though since you & your half-siblings "share blood" you should share a stronger bond. But the fact is... it's not there. Why? Well... you mentioned some possible reasons yourself. But the fact is... there's really no way to know for sure. So the best thing I can suggest is to simply let this all go & move forward with your own life. "Don't look in the rearview mirror. You're not going that direction." And, if you find you simply cannot accomplish this on your own, then consider seeking the services of a therapist with whom you can process what you have experienced & how you feel about it.

PsychCentral is a great place to get information as well as support for mental health issues. There are many knowledgeable & caring members here. The more you post, & reply to other members’ posts, the more a part of the community you will become. Plus there are social groups you can join & chat rooms where you’ll be able to connect with other PC members in real time (once your first 5 posts have been reviewed & approved.) Lots of great stuff! So please keep posting!
