Homygod I need to declutter but feeling paralyzed!

Does anyone have any good actionable advice/tips? Every time I start declutterring, the voice inside starts with “but what if you’ll need it later” and I end up getting completely distracted/blocked and then nothing happens. What do I doooo 😭😭😭 Literally every drawer, every cupboard is full with stuff. We live in a small 2BR apt with my mom and we have a toddler; I’m very early pregnant currently. I just know that something needs to be done. Can someone shake some sense into me please??

Signed,
