Hi Lilly, there's nothing wrong with wanting to detach/distance at times. After all you can only take so much can't you? But even legal highs that make you black out for a day or two really don't sound that good.
Maybe push on some more "healthy" ways to detach/distance when you really need to (alongside working through whatever's going on for you??). Even if they don't last that long then maybe the more you get used to them the more they will work for you. Now different things may work differently for you so just some suggestions to throw in e.g. something really active, swimming, yoga, mindfulness techniques??
But you know...you're not on your own, and we're here to help if you want to talk about things.......
