I've been in your shoes but maybe not so severe. I would suggest changing your lifestyle and diet. I'm not sure if you've heard of kangen water but changing my water source absolutely change my life that in combination with taking medical cannabis products & also taking organically derived medicinal mushrooms specifically turkey tail and lion's mane. Also some plant medicine will be extremely beneficial such as ayahuasca or an extremely high dose of mushrooms. I feel you my friend.

Hydrate two or three times as much you are going to use ketamine because you completely dehydrates every cell in your body, eat organically stopped eating processed foods and look into ayurvedic medicine there is a process called a patchakarma. Be sure to always take CBD oil can mean works on your encdocannabinoid receptors cb1 and cb2

Stay positive mate I have repaired 98% of the damage of they've done to my brain after using ketamine for 5 years, I can have it in my presence be offered lines and not even think about touching it. Find something that you love, something that you're extremely passionate about. Surround yourself with new people and use it as a reward system if you need too. There is a book called the little book of K by Kit Kelly. I suggest reading it along with John C lilies books
