What to expect from inpatient treatment

I’m at the lowest point I’ve ever been in my life, and my psychologist and psychiatrist are both recommending I enter a private hospital inpatient clinic for treatment. I’ve sent some enquiry emails and waiting for replies regarding admissions and waiting times, but I’m terrified of what to expect, and whether it’s actually going to help me at all. I’m hoping others who have voluntarily entered inpatient treatment can share their experiences and how much it helped them? I desperately need reassurance that this is the right thing to do.

A bit of background about me and what’s been going on: I’m nearly 34, have been struggling with severe mental

health issues since early high school, misdiagnosed for many years with “treatment resistant” depression and anxiety, and with BPD in 2020 just before covid shut everything down. I was diagnosed with ADHD in 2021, which finally explained the difficulties I’d experienced my whole life - feelings of constant overwhelm, burnout, emotional dysregulation, executive dysfunction etc. A few months later I was diagnosed with CPTSD, which fits my symptom

profile better than BPD. My psychologist also strongly suspects I have autism and OCD traits.

This year in April I had a major accident and fell down the stairs in my home, I broke my foot, sprained my spine, dislocated my shoulder and broke my arm. Subsequently I’ve developed frozen shoulder as a secondary injury. I’ve been in daily pain since April and have been off work since June. I’ve developed a trauma disorder since the accident - I don’t meet the full criteria for PTSD, my psych has assessed me as having severe adjustment disorder with complex depression and anxiety.

In short, I’m not coping at all. I was already struggling before the accident, which has now significantly exacerbated all my other issues. My relationship with my partner of 4.5 yrs has broken down completely. I’m not sleeping or eating properly, I’ve lost a lot of weight, I can’t take care of myself at all, which is adding strain to my already extremely burnt out and exhausted partner. I have SI every single day - it feels like I’m being crushed, I’m drowning, and any time I get a glimmer of hope something happens to shatter everything into pieces again. I’m tired of having to start all over again, again and again. I’m tired of being “resilient”, I just want an easy run for once in my life. I don’t want to feel alone in my suffering all the time.
