CBD is gonna help you for depression and anxiety (and hence much of the negative symptoms you'll get from the bipolar). ACDC (which only features high CBD phenotypes/chemotypes) is a good idea for that reason. I am not sure whether CBD is effective in the literature for the herniated disc although I know it is effective for some kinds of pain condition.
However, if you live in a legal jurisdiction and can get tested meds with certificates of analysis to show you levels of terps/cannabinoids/etc I would suggest that you look more specifically for meds whose test results show they have high levels of CBD. Varieties (strains) frequently have multiple phenotypes which can vary in the content of the resin they produce. This is before we get to differences in resin production/content/concentrations due to cultivation and environmental factors! It is a real crapshoot so if you can, use those test results and avoid anything that doesn't come with them.
We need to move away from looking at the strain and start looking at the test results for the meds we just bought to see specifically what they contain! Of course, make sure to look into the testing facility doing the tests and ask lots of questions at first about your meds.
Ask if there are pesticide/fungus/bacteria tests etc.
If you are not in a legal situation and can't get tested meds, it is a lot more difficult, I would stick to trying to get material of well known CBD varieties like ACDC whose phenotypes may vary in concentrations of CBD vs THC, but which can be relied on for CBD in worthwhile amounts in any case. Sadly, in an illegal scenario finding good CBD meds is more difficult.
Please note that IME, CBD predominate meds are not going to necessarily help you on the insomnia side of things. For that, may I suggest you start learning to make reclaim with AVB and cleaning your vape parts. Basically, recovering leftover resin that condensates on your vapes/bubblers as well as extracting from AVB is a very cheap way to get your hands on potent, sleepy meds (even if they taste pretty shitty lol). There is a wealth of information on this site about this stuff. If you have any questions about anything I've mentioned here, please do ask as I am sure this post is far from complete!
As to the herniated disc, I have not medicated this sort of condition before and will leave that one for folks here who medicate these conditions to advise
