I can't even trust my own mom anymore?

I think it's best if you do I had a problem with my friend only she loved to gossip so I ended up sharing my feelings with my sibling or therapist even a best friend until your mom stops drinking don't tell her anything that makes you look bad unless you have to. If you do share things with your mom when she's drunk she's going to blurt it out that seems to happen when she gets drunk so I would just give it a break and if she asks one day tell her why but do not go off and say mom I'm not telling you anything.
