Help Would this cause my death?

[Me Me Me]

Sorry for my previous somewhat disorganized post. I am new to this forum and I am planning my suicide. I plan to do it this week so time is running out. I'm terribly afraid of doing it and I don't think I can do it without an altered state of consciousness, so I plan on drinking copious amounts of alcohol and smoking weed to get it done. my method? I am quite poor and I do not have access to things that many say here and I only have medicines. I have: Naproxen, Acetaminophen, Aspirin, Antiallergy, Ibuprofen and Lanzoprasole. My mother suffers from many diseases, so she has several stronger medications such as opioids, but they are inaccessible to me. A few weeks ago I went to the psychiatrist (after two years without going) and they prescribed me: olanzapine and carbamazepine. Tomorrow I'm going to buy them, so I'd kill myself with a cocktail of:

Naproxen, Acetaminophen, Aspirin, Antiallergy, Ibuprofen, Lanzoprasole, Olanzapine and Carbamazepine. Added that I will be very drunk and drugged.

Do you think this could cause my death? I previously tried to kill myself and failed miserably and only got months of internment. I don't want to fail, not anymore. My situation is worse than ever in my life and I don't want to exist anymore. Please take the time to read and respond to this post. I would appreciate it.
