Family Issues Support Group
Family issues is a huge range that go from minor conflict to major misbehaviour and even abuse on the part of individual members of the family occur. Whether you feel you are in a dysfunctional family or you're dealing with a very specific issue, this is the place to talk about it and find others who might be going through the same thing.
My advice is to form a line of communication. Maybe meet mom for coffee once a week or call her. If possible try to start a tradition like having dinner once a week or once a month, or shopping together. Something that will give you time to catch up. You each have your own lives so don't try to live hers, but do take an interest.
Also don't forget to learn to love yourself and focus on creating your own life. We don't always get approval and that is normal, also we don't always agree with our mothers and sometimes it is better not to share everything about us, because we know that they don't understand anyways. Live your life and be happy for what you have accomplished.
It stinks when our family doesn't share in our successes and I understand that even at 27, there's an emptiness. Like if you ever have kids, you'll feel a loss if your mom isn't there to be a grandparent.
Ever try to have an open conversation about this with her? Not to blame, but just tell her you wish you were closer? Ever consider going to therapy with her?
