Sorry- Please clarify-
Are you actually us how you can give yourself a heart attack , in order to kill yourself?
Well I don't quite think that is a type of common knowledge that people on an "emotional roller coaster" really should know.
(There is really no way to induce a heart attack anyways).
Are you currently under the care of a psychiatrist?
Well becker- I am sorry but there is no way to self induce a heart attack.
Even if there was, my advice to you would be that you need to seek additional psychiatric help. If you are not getting results with your current psychiatrist, you should discuss this with him/her or seek additional help.
If you are actually making plans to harm yourself, my medical advise would be that you need to seek medical and psychiatric help immediately. As in tonight.
I am not as concerned about my being responsible, as I am that you are considering doing something rash and harmful to yourself.
I will opt out.
I would again suggest you talk to a psychiatrist.
