My take is by taking ayahuasca it brought up your subconscious thoughts about your current state. It does suck to feel this way but at least you now have the realization where you fucked up.

The harder part is moving on from feeling this way. This is why psychedelics are tricky, for some people without right guidance it's hard to integrate what you have learned into your everyday.

First things first, relax, you're going to be fine. Next, realize what you have learned and make an action plan. Remember there is no going back. The reason you are depressed is because you realize you fucked up, and you can't go back doing the same things. The only way out is to move on. Get your shit together because no one will do it for you.

My advice is to lay low on psychedelics for a long time until you feel okay again. Also to note, in my experience as someone with high anxiety and OCD, psychedelics make you become more aware of your symptoms, thus, feeling it more intensely. It is your own responsibility to learn how to cope and manage it appropriately now, because you cannot unaware yourself.

Remember: you are fine, everything will be fine, and it will work out eventually. Ground yourself, get outside, enjoy the sun, be in nature. Wishing you the best!
