Late Period due to Mental Illness

So

Hey 💙 I’ve been in a really awful depressive episode this past week or so - I tend to have poor mental health during my PSMing, so feeling low is quite normal for me once a month. However this time my period hasn’t come, it’s 8 days late and I’ve never been late before so I’m starting to worry a bit.

If anyone has any advice as to what to do that would be really helpful, I can’t imagine my worrying about it is doing me any favours either!

(I’m not sexually active so there’s no chance of pregnancy, just to clarify!)
