I (28F) can hear my (75+F) neighbour crying very loudly most nights of the week

Myself and my partner bought our semi detached house back in Jan/Feb, we introduced ourselves to both of our elderly neighbours.

To note, the neighbour in question was lovely and accepted our baked goods. The only thing we remember of note is that she had very obvious blood clotting in her entire legs (they were almost entirely purple and swollen) and that her house smelled like TCP. She lives alone but has carers going in semi regularly.

Now the issue, she cries/groans/screams in pain SO loudly 6/7 nights a week… Sometimes she is so loud it wakes me up from a deep sleep.

To note, it’s not the being awoken by these screams that bothers me – it’s the panic that she might be dying. Every night I lie awake and panic wondering if she’s okay.

Anyway, I’m pretty socially anxious and British so naturally I’ve not addressed it to her head on, I don’t want her to feel worse! So last week during a particularly loud, terrifying bout at around 4am I contacted the police to do a welfare check – they went round and I heard her answer the door and confirm she was fine.

The issue is it hasn’t stopped, what should my next move be? I can’t afford to sell my house as I was made redundant in February 👍

TL;DR – elderly neighbour sobbing at night, I’m tired of worrying about her mortality.
