>>81774709 (OP)severe social isolation and physical inactivity is noted to have a negative impact on all cognitive functions including memory, reasoning skills, and emotional expression/sympathy. Which can be exacerbated by a poor diet, irregular sleep schedule, and poor hygiene.
If you experience any of these listed effects/habits then it can be a sign that bedrotting/neeting is the cause for a lot of your problems.
However, being only 28 and not being able to recall ANY of the names of people you knew could be a sign of a worse problem. such as severe depression for example.
In worse case scenarios it could be a sign of something much more deeper and much more severe. Such as a brain tumor or brain damage. I would recommend seeing a doctor if such a problem is a serious concern of yours. especially if you have a family history of brain damage or issues, or severe drug usage, or even head trauma in the past. Even a regular check up could probably do you a world of wonders.
