Need help with vibrator

Ok so I’m 15 and masturbate because it helps relieve stress and reduce my anxiety but I’ve never been able to to orgasm and it just makes me even more stressed and I really want to try a vibrator too see if it will help but idk if I should talk to my mom or not. I know she’s really understanding and is fine if I masturbate but I just don’t know what to do and it’s stressing me out
