Your situation sounds similar to mine. I've been away from my noisy and abusieve landlady for years but when I'm under stress, the problem recurs. I have the impression that I get a thinner skin (both literally and figuratively) the older I get and that each new fit of depression and anxiety leaves me more vulnerable to the next. On the other hand, I have gotten a lot of practize in suppressing those fits, so I there is a silver lining.
Positive routines are extremely important. My sister swears by a bath, I prefer a cup of tea or warm milk with honey, a good book and a lavender scented candle. In May I always have a big bunch of lilac in my bedroom, and in February a few hyacinths but not everybody likes the scent.
Warm milk and honey was great for a while during the trouble. Drinking it slowly is the best way to fall asleep quickly but sometimes the effects weren't long lasting for me. It was really nice though.
In the fridge, I've currently got kefir and cherry juice. In the past, I had soya milk, coconut milk and almond milk to combat the stress/eczema symptoms. They had varying degrees of success like the warm milk and honey above.
If the local government/authority had dealt with the noise problems quickly then I wouldn't have developed certain symptoms. I outlined the health difficulties that I was experiencing at the time and they got progressively worse.
The local government/authority had the nerve to urge me to see a GP about my health. They were 'more than happy to help' with my symptoms (that they partly caused due to a lack of action) but offered no solution to stop the noise. In their mind the situation wasn't serious. They had no intentions to tackle it.
Originally, they'd told me to see a 'victim support councillor' when I dealt with the first noisy neighbour. Talking about it just frustrated me even more because the situation just dragged on and on. The service is supposed to be for victims of crime, but in the end the local government/authority said there were no signs of criminal activity. They were willing to pull the same schtick again with the second noisy neighbour instead of punishing him. He's got a long history of violent behaviour in bars.
That's why I'm struggling with physical/emotional problems now. It was hard to recover physically from the sleep deprivation while I was being gaslit/isolated by those whose job it was to help.
It sounds weird but there were times I had to crouch down in the street because I was in so much pain from walking. Not even long distance. Three years ago, I had a threshold on how much walking I could cope with. I could handle a few hours if I had time to recover afterwards. Now, I've got to plan my outings because the pain threshold doesn't exist. The local government/authority engineered chaos and drama in an already stressful situation. They took away the recovery time and that's impacted my long term health.
Luckily, I'm getting the eczema under control and can last a week before the symptoms are unbearable. But it's not a consistent solution. It's still pretty much a daily chore to keep all of the symptoms in check.
The auditory hallucinations have stopped which is good. Hope they don't come back.
