Oh, I am so sorry that your family is not seeing the benefit that family counceling would do. I am sorry that you and your mother drifted apart. Please don't take that as that she doesn't love you, she just probably feels that because she struggles, she doesn't have the quality of mind to reach out to you.

Do you mind if I ask what your mother is diagnosed with?

I am glad you found PC, at least you can find people to talk to that understand mental illness and offer you some support. We are not therapists here, but there are many that understand mental illness, are in therapy and are actively working through their issues.

I hope that you find something to do outside the home, like extra art classes or something that can keep you busy during the summer. You need to be around people who are engaging life and away from the struggle of what is going on in your family.
You have to make the efforts to take care of YOUR mental health and not feel guilty about it.

You are not alone in feeling lost due to the mental illness of a parent. And it is hard for the teens your age because you have to get permission from parents to get help.
I think that there needs to be a better way that teens can get counceling and have it be "their" choice and be private.

Keep being strong for yourself, keep getting involved with people who are doing things and are active, you can't change your mother or her problems. You have to takes steps to keep helping yourself.
