Frustrated with Doctor's Insomnia Treatment Options

I'm getting really frustrated with my doctor. I've been struggling with insomnia since puberty and I've tried almost everything, to dumb extremes at some points. Melatonin, zzzquil gummies, pure zzzs, diphenhydramine (I'll come back to this one), doxylamine succinate, trazodone, topamax, Zoloft, quetiapine the list goes on. Diphenhydramine worked for a while but my body builds a tolerance to medications so obscenely fast that I soon found myself taking what should have been a lethal dose every night for 6 months. I was taking 40 pills 25mg each. I kicked that habit after even 40 wouldn't put me to sleep or make me drowsy, just drugged up. Since then I've been BEGGING for some kind of sleep aid and my doctor has only been prescribing pills that are mainly antidepressants or antipsychotics. I understand that some of these pills have sedative properties but after my most recent experience with topamax completely altering my personality and seemingly dumbing me down and taking a week just to get it out of my system after only taking it for 4 days, I'm starting to really be hesitant about taking these multipurpose drugs. Most recently she prescribed me olanzapine, disregarding that I haven't had any psychotic episodes or manic episodes in about a month (which is great for me!) and I already am having issues with my depression and suicidal thoughts (not so great). I'm scared. I don't know what the right thing to do for myself is right now. I know I should trust my doctor and try it but I also don't want to start a pill that isn't listed as a sedative (it's a side effect meaning it might not even happen to everyone and I'm commonly not affected by drowsiness as a side effect) and will take at least a week to even work. But then I keep jumping back to the "what if it does help though?" Then is it worth all of the other side effects and the fact that now my "sleeping pill" is going to be following me into my daily life? That's a big commitment just to try and sleep for the first night in weeks after every other "multiuse" drug has done nothing but break me down and take away my ability to actually think. Ive been seeing this doctor since I was 16, she knows very well the issues I have with sleep. And to be fair, I get why she might not want to prescribe just plain sleeping pills because of how addictive they are but even still, there has to be other options or at the very least couldn't I have a sleep study done? It just feels like she's completely ignoring my pleas for help and I'm being left to literally wither away mentally. If I could just sleep maybe I could get my life together again. if I could just do something.
