They are only 2 little kids. Your sisters and grandmother can help your mother to take care of them. Please, do it. Do you know what a great reward you will recieve if you do it? I read somewhere that since children are very innocent, angels approach them. So the more time you spend with children, the more you benefit from being close to angels. And by inviting them to your home, the angels will enter your house as well.
Start a podcast ...why not ?
It would be amazing if you bring topics related to the Ahlulbayt (عليه السلام) . You can do biographies on the Ahlulbayt (عليه السلام) through your podcast . That would be amazing
There is a reason why drugs is haram --> they mess with your head. Now DMT and ayahuasca are maybe not necessarily harmful to the "health" and pysche but they tend to come with weird experiences that influence your behavior and convictions. Supposedly shamans and other old magicians used these drugs to communicate with interdimensional beings (djinns basically) and coincidentally (no really coincidence lol) these "beings" always carry the same gnostic message of how humans are bad, save-the-planet empty words, basically waswas x100.
For someone to get closer to truth he/she has to resort to revelation(Quran,..) and reason only, not drugs (however good they made you feel).
