My DSis has significant mental health problems (mainly depression, anxiety, BPD also suspected) and hasn't been able to work for a couple of years now. She's getting married soon and plans on starting a family soon after. She sent me a text the other day saying that I have to remember she will probably always be mentally quite unwell, described herself as a hermit, said being outside her home makes her feel anxious and unsafe. She says she sleeps a lot and often can't do much, and has very little energy emotionally, physically and mentally. She asked me to think about how hard it is for her to even leave her house to walk the dog with her DP. This was in response to me saying I don't see her much and wish I saw more of her. Anyway that's fine and I respect her situation and mental health is what it is.
AIBU to be quite concerned about how she will cope with parenthood given how long-term mentally unwell she is, how difficult she finds it to be out and about and her energy issues? Tbh there's nothing I can do anyway and I've already raised it as gently as I can but I'm not sure she realises how hard parenting can be at the best of times.
