I discovered tonight a safe space. My car. I was teed off, very upset and it was raining and I couldn't go to the hammock to be alone, and sometimes of late even the hammock doesn't sooth because there's too much traffic noise.
I'm a person who loves utter silence. Well, no, not utter silence, just the silence of nature, sans all human sounds. Nature can be loud but it's a happy loudness. Well, unless it's a constantly barking dog.
So I sat in my car with the windows closed. Silence. I could lower the seat back in a position of repose. Turn the light off in the garage, a happy sensory deprivation chamber. Of course the engine wasn't running. My desire wasn't to 'off' myself, just turn off the extreme emotions and sensory anxieties until I could catch my emotional breath and function once again without being in extreme selfish, bitchy stress mode.
I offer it to you as a suggestion if you need such a place of quietude and respite. It may not be a garden with wind chimes, but it IS a place you can be alone, and stop the bombardment of external input. Though you'll still be stuck with your own internal chattering mind. I remember someone recently saying they wanted to be alone and so I suggest this "tool" if you will. It really helped me.
Oh, and you can lock the door if need be. Though I hope that's never needed by anyone for physical danger reasons. I mean it more as a kid's club house KEEP OFF sign emotionally. Hey, bring a pillow. BREATHE! But do open the window every once in a while. Stale breath exhalations I discovered are kind of nasty after about 10 minutes! lol
And always remember your sense of humor!
