Staying in a relationship for my own mental health. Is this a healthy thing to continue?

It sounds like you're asking if you should stay in this relationship because the other person is an emotional support person for you. Nobody can tell you what is healthy or unhealthy for you. However, I can tell you that learning the tools to manage your own mental health issues is the best way to be happy and independent in life. There is so much support out there now for these issues, and you deserve to be happy and strong, standing on your own without needing anyone else. Relationships are about give and take. Otherwise, someone will burn out eventually.

Providing the relationship is a healthy one and not a trigger. You should only be in a relationship if it makes you happy. A relationship is something that you should feel supported in and not something that contributes to you feeling lost, lonely and sad. Staying in a bad relationship can fuel your mental health leaving you anxious and depressed. Whereas being in a healthy relationship can help you to flourish especially when that person accepts your mental health and holds your hand through it. If it is a trigger, you should figure out how to terminate it so that you can heal. Your self care is key to feeling better.
