Hello

I'm sorry you are struggling with depression lately, I understand that feeling uncertain and are hurting from what your friend has said to you.
On the tools page there is certain ways how cope with it and listening with empathy and don't be invalidating.
The hardest part for me was not taking things personally with my partner but on here some people has said it's like trying to think of speaking to them as a inner scared child. it sounds like something has upset her or caused a trigger, And sounds like she's splitting at the moment. there is also how to help with boundaries that you can also start to use to help with what you need.
Like my partner is in a rage and sating not nice things "I know that your hurting and your mad but I can't talk to you like this, I'm going to message you later" or along those lines. Sometimes things can get better but it does take patience and sometimes be worse.
Do you feel a little uncertain what you want to do?
If she's seeing a fear of abandonment sometimes they become impulsive, and can have a reaction and behave in different ways to keep you there, like a teenager who you just said you can't go to a party, sulks, acts out, different ways.
We can't control others reactions but control our own it is easy said than done. but you can start looking after yourself to help you start healing also if you have had advisement from your health professionals there is a reason they are saying that to you.
I'm still learning alot my self there is alot on here that will help you read different posts.
Take care
