Of these methods, hanging is the best.
Cutting the wrists is not effective.
You can also hurt yourself and have problems with your hand.
I highly do not recommend it.
Meds, it's hard to say because you didn't say what you mean.
If you mean things like ibuprofen, paracetamol, etc. it's a VERY small chance of dying.
There is also a high probability of permanent internal damage.
Of course, also a lot of pain.
Hanging is simply the best of these options.
However, I do not recommend using a sweatshirt.
I think you can get something better.
I also advise you to read about this method.
You need to know what to do and how to do it.
The more prepared you are, the better.
Good luck.
