My mental health has been low recently, and I'm in a stressful time at work and feel like I can't cope with it. I have been in contact with my GP and have been prescribed antidepressants but have been told they can take a couple of weeks to start working.
I think I may need to ask to get signed off from work, but I'm worried about doing so. How would I tell my manager? Would I ask for a call to explain it? Would I send them a letter from my GP? Will it negatively impact me getting another job in the future if it's on my reference?
