Hello why me. Welcome to psychcentral.

I am sorry to hear that your mother isn't being supportive. I am not certain that I have any valuable advice but I will try.

Have you tried thinking about what it is that is bothering you and then waiting until your mom and you can discuss the issue calmly? When I was younger I often wanted to settle issues right now and I found that didn't work as well as when I thought through what I wanted to communicate and was less emotional before I discussed the problem.
