Multiple accounts in collection, unsure of how to handle it

I don’t have a high amount of debt unpaid, maybe 12k at most. I have 5 accounts and collections and others heading there. I have thought about bankruptcy but it’s a small amount I don’t know if it’s worth it. My credit is pretty bad and I want to work on improving it for the future. I was reading about asking about debt verification and that some companies might decide it’s not worth it and remove it. I am looking for personal experiences and advice.
