Sorry to hear of your trial! I escaped NYC just in time to crash on the coast where it is more conducive to recovery. Yes, people have recovered from this stage, but you'll have to take charge of your own recovery.
We all come to a similar place symptomatically but from different causes and triggers. Meanwhile applying other people's advice often doesn't work, or at least at your current stage.
All I can tell you gereally speaking is the most important thing that worked for me at an early stage (also with bad insomnia) was coffee enemas, which I resisted doing for a year.
What has gone further in healing and rebalancing is:
1. rest and eliminating stress
2. reducing inflammation every where I can find it.
3. detox detox detox (CEs + diatomaceous earth + electrolytes + probiotics)
4. a methylation program involving B12 + folate + cofactors--but other imbalances should be corrected first before attempting this.

Taking lots of magnesium citrate or glycinate or malate is the safest thing you can do for your sleep and CNS now, unless you can identify a cause. But most causes involve elevated histamine, cortisol, glutamate et al which can be brought into balance by the above. Identifying and laying off foods that you are sensitive to mean time will help.
I would go very easy on high dose supplements at this stage as the can cause other imbalances. Low and slow.
Last, 23andme will give you an owner's manual for your body. Whatever shocks you have dealt to your system have probably caused genetic fractures along stress points (SNPs) and these can be specifically treated nutritionally without years of trial and error. (Check out Phoenix Rising.)
Good luck!
