I'm curious, are stepsiblings like real brothers or sisters? I have a stepsister, and while I care for her I'll always consider her my STEPsister. She and I did not grow up in the same home. I only visited my dad weekends and holidays. Its strange cause I am so close to my dad and I did not live with him as a child, and I've grown closer towards my stepmother and even consider her "mom" like despite all the problems we've had in the past. With my stepsister however we've gotten closer with her opening up to me more. But still I don't think of her as a sibling. I think of her as part of my family. But she's more like a cousin to me than a sibling. Thats not a bad thing cause I have cousins that I'm real close to. But I do think my dad is what holds my stepsister and I together. If he were to pass on, I doubt my stepsister and I would have much of a relationship. He and my stepmother are the ones that encourage her to be more social and engage in conversations with other family and myself. I think it might also have to do with our personalities. I'm a very social outgoing person. My stepsister suffers from depression and just being around family other than my dad and stepmother makes her nervous. As a teen she barely spoke to me when I would visit my dad. I think that might be cause of her depression cause she avoids other family as well, not just me. Her medication helps and since she's been on it she's been more talkative with me. But because my stepsister and I never established any kind of bond when we were younger, I think I'll always think of her as my STEPsister, and not like a real sister. Its too bad cause both of us don't have biological siblings. But considering the circumstances, realistically I think seeing her like a cousin is the best I could hope for. And at least we get along.
