That's a lot to be hit with all at once. I hope you find someone to talk to, be it an extended family member, doctor, therapist, or whatever. At least you can reach out here in any event.

And if your mom is suffering from depression, getting her some professional help as well would be the best thing for the both of you. As someone who has been diagnosed with depression for years, I know that I have to make myself better. My family can't do that for me. They can only support.
