Say you stay awake all night, or not eat correctly, or just forget to take care of yourself. Is this considered SI?

I know what I have said in the past about asking if it is SI, but I'm curious about what people think on this topic.



On another side note.
Overall this week, I have had a Crappy week, full of SUI thoughts. It's getting to be way too much for me. Not to mention all of the things I have discovered this week.I am tempted to just stay up all night, and find something to do. I'm going to try to exercise tomorrow. But as for tonight, I'll just try to not give in to the SUI thoughts. and no hospitalization is not a good idea for me. I will see my T tomorrow. and If I Need to I'll make an appointment for Friday if need be.
