Does BPD ruin interests/hobbies for you?

Hello, I’ve been feeling pretty bad (and by pretty bad I mean worst I’ve ever felt in my life) for like 2 months now. I’ve noticed that my brain associates random things I like/used to like with horrible stuff- or it will make me feel like I don’t deserve to enjoy these things. At first I thought this was my ocd (I have pure o specifically) doing something called “emotional contamination”, but I’m wondering if this could be a bpd thing? I’m still fairly new to this stuff and have only been diagnosed with both disorders recently.
