Doing IT support in the average organization is more often than not a heavy burden on mental sanity. Your post is direct proof of it. From your report it sounds like it's actually a side responsibility and not your main task. This is actually the first red flag: It opens you up to a lot of psychological abuse and gaslighting attempts from co-workers (as seen in your post) that will directly impact your performance on your non-support tasks. I'll list some points that are a must in any sane IT support organization be it internal or as an external Managed Service Provider: - You're working in a team of support people. You can discuss your current tasks with them. One of them can take over if you get sick. - You're working with a ticketing system. No support is provided without opening a ticket. This is for documentation, time reporting, reporting abuse etc. - You're having a boss that knows how IT support works. If the above is not given it will take a toll on your health sooner or later.
