Your friend is not in a good situation. She is aware of it. Until she takes action the situation won't change. I have been in that place of complaining to friends about A or B. But only me can make a change. Complaining is good if it is followed by action, otherwise it is just an extension of suffering. You can't tell your friend what to do, but you can support her in the decision of changing her life if she wants. Usually people make a change when the suffering becomes unbearable, when health crumbles, when illness appears. I hope that your friend won't wait until then, it would be a pity. Life is full of oportunities. We can always change

Blessings and have a splendid day🤗
