Yes and no, maybe that's further into things, like self-care--the point where you are a bit more stabilized and trying to keep yourself in balance when things begin to get really rocky. Stabilization at the beginning or when things are at their very worst, honestly, for me couldn't be done on my own. It involved reaching out for help, it involved medication, it involved learning what my triggers where, recognizing when anxiety was sneaking up on me and what tools I could use in the moment to bring it back down. I learned to pay attention to my thought patterns and was challenged by my therapist on many of them.
100% at my very worst, when I needed stabilization I had to cling to someone else to walk me through it. I would have never, ever been able to do it on my own. Find an arsenal of the themes stated above and use them, they will help. Put life on hold the best you can while you get your head above water, but do not shut yourself out from the world because it will cause you to sink further. So, for example. If you can, cut down work hours, extra commitments that cause stress, ignore the messy house, etc. But make sure you go for walks, go get coffee with friends even if you don't want to, etc.
I'll attach a link, the beginning portion helped explain why clients really can't do the stabilization for themselves on the onset. The first couple paragraphs are really helpful in understanding that. The rest of the article might not be that useful.
