So to keep it short I am wondering if there is a name for this “blanking-destruction” as I do it pretty frequently.

I am usually good at working towards my goals but I have these moments (often when I’m tired or overwhelmed) that I “blank”.

In these states I do things that are self destructive. Not physical harm but more so “giving up” and giving into my vices (not drugs or alcohol as I don’t partake in those) I’ll shut down my studying and binge watch irrational tv. Or basically do things that will sabotage myself. I found I feel anger or frustration in these moments but I’m unable to link them to anything.

The day can be going wonderful but then I just “snap”. I don’t know what to do. Is there a name for this so I can look into this? 

Many thanks
