Is it okay to tell my mom Im depressed through text?

A text is a lot less impersonal that saying it to her in person. That doesn't mean it's not okay to text that information, when I am in need of help with my depressant mood swings I text my friends or family how I feel and they help me over the phone. If you are just looking to tell her, not seeking any sort of comfort, it is perfectly fine to share that with her over the phone. Hope this helped! :)
