Hello...and welcome!
I was in the same situation about 5 yrs ago! I'd kill all my houseplants.... too much overwatering. The past 3 yrs I've managed to have a few houseplants that are still going strong. I have pothos, spider plant, and aloe vera. I water my pothos every 2 weeks as well as my spider plant. I water my aloe vera the 1st of every month... I give it a good watering and keep it on bright (not direct) light. I've also bought a few more succulants and I water them every 3 weeks. I put a reminder on my calendar when to water my flowers. By keeping that same schedule... I've managed not to kill the plants. I hope this helps.
