Hi ParkerLauit,

Welcome to psych central. Thank you for sharing with us.

It is hard to mend relationships, but possible, if you really want to. It looks as if your Mom loves you and is scared for you. Grounding you is probably all she can think of to keep you safe.

Trust needs to be earned, so if you want her to trust you again, you will want to show her in small ways where you can be trusted. Studying may be a good way to start.

Maybe start to talk to her about how you can keep yourself safe when the grounding is lifted?

Do you want to be safe? Weed and alcohol can be dangerous, especially in a young brain.
When your brain is fully grown (age 21 to 25) then these things may or not be ok for you. They can both cause severe mental illness in a young, developing brain. I personally know a couple of people who had severe mental illness apparently triggered by using weed, (hallucinations, delusions etc. Which didn't go away) and modern varieties can be much stronger.

Are the people you hang out with helpful if they encourage you to use these things?

It will take baby steps, but I hope you can start to rebuild your relationship with your Mom. If you stop using mind altering substances, therapy is more likely to help and you may be allowed to restart it. It's all part of earning trust.

Good luck and keep yourself as safe as you can. You're important here, and to your Mom.
