That description would somewhat better describe Si. And before anyone comes at me for this - yes, Si egos aren't as oblivious to the future as much as many would like to believe. At the end of the day, which is the type most likely to neurotically schedule their day ahead and make obscenely detailed plans related to the future that they stick to and dogmatically follow? It's them, namely SLIs as well as Ni PoLRs.
Having low or little to no Ni is what's actually bound to compel you to actively worry about the future more than having Ni high up our fxn stack. As for actual Ni egos, making a mental model in their heads re: how things are likely to play out is an automatic process they don't struggle with so there's often less anxiety involved what will come or "the future" archetypally.
As for the actual question at hand - no, not really. All people have a natural proclivity towards feeling emotions (intensely or not), regardless of their type. One of which being "depression". It could be just a fleeting moment of it and/or often is something that's been directly caused by your normal reaction to environmental circumstances, at the end of the day we're all human beings.
When it reaches a point of becoming habitual and prolonged enough for it to roughly fit the diagnostic criteria of what we might describe as clinical depression, then we describe it as such but it's not at all type-related. The notion of clinical depression in of itself is relatively subjective too since it's all essentially dependent on someone's personal interpretation of behaviour symptomatically as per DSM or whichever other manual in relation to the abstract idea of the disorder. The causation could obviously also be simply related to someone not being neurotypical (the problem being rooted in one's brain structure) but that isn't required for a diagnosis.
It's also quite odd you've begun to type yourself IEI since you're likely Ne ego, hence this seemingly unrelated connection between depression and supposed Ni usage.
You've also been typed EII/IEE more than enough times among other online Socionics circles (maybe not this forum particular). That's not to say that social consensus should dictate truth or that correlation always equals causation but as far as i'm personally concerned, the case of your type is one of the few i agree with a lot of the Discord typists with on.
