My first time posting here as well :)
If your depression/anxiety is affecting your work then yes, definitely speak with your manager privately, however, your colleagues do not need to know. If you feel comfortable telling them then sure, but I would suss out first their character/personality - are they mature enough? Do they believe in mental illness? While mental health awareness has come a long way not everyone takes it serious, not everyone believes it’s a real thing! (I’m married to such a person).
I have suffered anxiety, depression since my teenager years. Never knew it then though. I’m 42 now.
I was diagnosed with anxiety 6 years ago when I found out my husband had an affair. Since then anxiety has never been to far away... it will lay quiet sometimes for months only to resurface in full force, sometimes for no reason, other times because of what’s going on around me.
so as I’m writing this my depression and anxiety is fully awake. I have had 3 days off work & really don’t want to go back at all.
I have made my team leader aware and while she has been understanding I can’t help think she’s not getting how debilitating this can get. Maybe she does and it’s just my own paranoia, me analysing everything she says or does not say - I do my own head in!
The point I guess I’m trying to make is this:
It is important to let your boss know about these issues when they arise and only if it is going to or is affecting your work.
if you have an altercation with an employee or feel they are making fun of you then address everything with your boss - let them know then. I would not recommend telling them unless it is affecting your ability to do your job.
Sorry, probably didn’t help you at all :(
