So I’ve been looking into self sabotage, the causes, signs etc. Things like alcohol and drug abuse, binge eating and self harm keep coming up.
This got me thinking that maybe self sabotage isn’t the correct definition for the behaviour that I have in mind, and am now wondering if it may be classified as something different? Any help would be appreciated.
I’ll now give an example of the behaviour that I am talking about:

There is a person. This person has suffered with anxiety, depression and anger. They have experience some mid life trauma and have managed, with the aid of medication and therapy, to overcome these problems. The person lives a successful life (whatever that means) and for the most part functions very well. However the episodes of anxiety, stress and worry still occur occasionally, triggered by certain things. Now, this person will put their energy and time into something, be it through educating themselves in their professional field, purchasing a house, going for a promotion. Their actions thus far are relatively “normal”. But here’s the key: When something doesn’t go as they had planned, say the loan didn’t come through in time for the mortgage, or the deadline for the course passed unnoticed, or they didn’t get the promotion, this person would then start to intentionally fail at other aspects of their life. It is very much a “Well if I can’t have this then I don’t want anything attitude, and they will proceed to sabotage other goals that they have, any projects that are in progress, or at least give up on them. So if something failed, even if it was beyond their control, they would try to drag everything else down too, even if it was to their own detriment.

So you can see why I’m thinking that this is self sabotage, but I can’t find reference to this behaviour and mindset anywhere in particular.

Any ideas?

Thanks
