I've just sold my house down south, put my furniture in storage and moved in with my parents temporarily in the north while I look for a house to buy there. I wanted a fresh start after my youngest child started uni and I no longer needed to be near my ex to co-parent. I was in a relationship that was going nowhere so I'd had enough of that too I'd hoped to take some time (finally) to rest and focus on myself for a change, do a yoga retreat, reconnect with friends, etc. Instead, my move has coincided with my sister becoming seriously ill after complications after routine surgery, so I've ended up having to look after her children while she recovers, as I am self-employed and work from home. Her ex took some time off work but needs to go back now. My parents pretty much volunteered me for this role. Had I been asked I would've said yes but I wasn't given that courtesy, it was just assumed. The thing is, there's no one else who can really help. My parents are elderly with health issues and my other siblings work in employed roles and don't live nearby. It could be weeks before my sister is discharged but she'll then need rehab. I've been putting my life on hold for years to get my own children through school/college, now I'm having to do it for my nieces. I feel for my sister of course, but really want to forge ahead with my plans to buy a house and start living my life for me for the first time in decades, not feel like everyone's personal slave. Am I being unreasonable here?
