Nervous to tell family I’m pregnant

Having a hard time figuring out how and when to tell my sister I am pregnant. (6 weeks)

For context. We are 2 years apart. My older sister is autistic and has severe depression. She is behind in life in most ways. 😔 Most of the time I feel like I am the older one.

She is sensitive and has always been attached to me. Whenever something major in my life changes, it affects her deeply. She has told me before that she does not want me to have kids. I don’t take it personally. I know it’s not coming from a bad place. She is scared we will lose the closeness we have. I think it also makes her feel even more behind in life when comparing hers to mine.

I truly believe that when the baby is here, she will love it….. But I am scared that telling her I am pregnant will send her into another emotional breakdown. I don’t want this news to hurt her or make her feel like she’s losing me. Has anyone dealt with something similar? I want to share this happy news but I’m so anxious about how to do it gently. 😔
