Is this kufr? Will Allah forgive me after doing tawbah for kufr?

Aoa 2 years ago i was interested in reincarnation and Started to think that we could also do reincarnation and stuff and i even tried looking into my past life but i left it since 5 months ago..Alhumdulilah but today i got to know that this is kufr and is this really kufr? And after that i got super depressed..i wanted to cry but i couldn't so what i did was i went to the masjid and i prayed to rakats of salat al tawbah and promised Allah that i will never commit this sin again and i even told it about to my friend but i am so frightened that Allah won't forgive i did tawbah and promised to never return to it please for Allah's sake please tell me did i do good enough? Will Allah forgive me? Jazak Allah
