Getting rid of old papers

I’m 6 years out of a toxic abusive relationship. I’m also a hoarder. I am starting to tackle my hoarding tendencies, and many memories are being brought up. I have love letters and birthday cards from him. I have journal entries detailing some of our worst fights and the shame he made me feel. What do I do with it all? The love letters make me feel like I’ll never find someone to love me again and the journal entries are just triggering. Should I even read through these things agin or just shred them?

Thanks
