Im 100% serious i need ur help
If you are already diagnosed with autism then you should speak to your doctor. Any form of drug abuse will affect the medications you are already taking. It is necessary to peel away the layers of what is bothering you.
We use new behaviours to cover old one so that we don't see them. This newest problem is just that. There is something you don't want to see so you blind yourself to it. Using an excuse to cover a reason.
Don't feel bad FOR your brother. Help him. He chooses to do the drugs, just like you. If you seek help with your problem, as minor as you say it is, then he may get the initiative to seek help because his situation is worse. Show him the path. But if you aren't willing, how can you expect him to be either.
Step one is tell someone there is a problem. You talk to a doctor about yourself and talk to your brother about the appointment's result. We don't help anyone when we don't share the information. If telling him doesn't change his actions you may have to do an intervention and tell your parents.
Neither of you are alone. there are millions of people who suffer from the same problems. You just need to reach out of your bubble to help yourself.
you probably need therapy and be on different meds maybe Prozac is not working for you try zoloft
i have major depression and ptsd
go to rehab. that would make everybody so happy to see yourself getting help. plus it would help you.
