If I were you, I would either start tapering with what you have left, contact the pain clinic you were referred to and explain to them that you will be running out of meds soon.
Until then, tapering off or asking your primary for something to ease the withdrawal symptoms might be an option.
Who told you tapering off morphine is dangerous? Morphine is an opiate, like other pain medications. It is NOT dangerous unless there are severe underlying health conditions such as unmanaged high blood pressure or unmanaged heart conditions. Millions taper off opiates with no issues. Even in a sudden stoppage of opiates, in general, it is uncomfortable, can cause sweating, chills, diarrhea, muscle spasms, feeling flu like for 3-5 days, with day 4 and 5, feeling improvement in symptoms. NONE of those symptoms are dangerous, and can be managed by OTC meds, and supplements.
Tapering is a process of slowly lowering the total daily dose of a medication, and managing/minimizing withdrawal symptoms.
A proper taper should produce little to no withdrawal symptoms. However, any major reduction/stoppage done suddenly can cause withdrawal symptoms lasting 3-5 days.
Primary care doctors these days often will NOT prescribe opiates, except for a few days.
I still recommend you start tapering BEFORE you find yourself facing a sudden withdrawal due to running out of medication completely.
If you find a new pain management doctor, then you will have also lowered your tolerance for opiates and may find them to be more effective at lower doses.
Sudden discontinuation will likely in most people taking opiates for a period of time WILL cause withdrawal symptoms and increased pain.
That is not new, it is a well documented effect of long term opiate use.
Opiate withdrawal, by itself is unpleasant, makes people feel like the worst flu they have had, but is not typically the cause of suicide. That is typically a mental health issue, not a result of physical dependence or issue directly related to sudden opiate discontinuation.
The FDA has recently required lots of new warnings regarding using opiates, not all of them are justified in my experience and claiming that those who stop taking opiates are suicidal or become suicidal is one that I feel is related in most situations where legitimate pain patients fit.
The political environment around the use of opiates in treating pain is overblown, and often intertwined with use of heroin, over doses, and other abuse of poly pharmacy drugs.
I hope you find help, but whomever told you that morphine withdrawal is life threatening is scaring you unnecessarily.
Withdrawal can be managed, tapering is not impossible, and properly supervised by a doctor is entirely doable, at home, with minimal symptoms.
