I see really mixed thoughts onayahuasca, some people say it's really good for understanding yourself, but I have also seen a lot of people saying it can cause depression and lead to su*cide
You should decide for yourself. You can get facts and knowledge about ayahuasca anywhere, but when you take it you have to be sure that you really want it. If you're not sure, don't take it, it won't end well.
I suggesst you start with DMT, the active ingredient of Ayahuasca. DMT is easily metabolised by your body, but Ayahuasca contains chemicals that block the enzymes which process DMT making it last for hours. DMT only lasts maybe 5-30mins depending on the person, but its pretty much exactly like Ayahusca. Think of DMT as a trailer to Ayahuasca the movie.
