I think it may help to try and expand on your inquiry.
Do you remember anything at all? Tell us step by step what occurred, some pieces may pop back into your mind if you do your best to recall as much as you can from start to finish.
Why do you feel broken? Why do you feel different? It might help to expand on this. It is hard to know what to fix if you don't know what is broken or different. Was the experience just overwhelming for you?
Everything is ok. You just went through an odd experience with DMT. DMT is just weird and odd and bizarre. Perhaps your dose was on the higher side and you simply had a 'white out' experience. It happens. If you are interested in trying DMT again I would suggest researching DMT, reading some experience reports, and start with a low dosage and work your way up to a higher dosage when you are better acclimated to the experience of DMT.
In the mean time, relax and give yourself some time to integrate your experience as Exitwound has suggested. Try and laugh it off as a weird thing and move on from it. No need to fret or worry.
