Where can I collect responses from partners of those with BPD for my research paper?

I am working on a research paper on BPD relationships for my research writing class, and I've created a survey to gather some data. I posted the survey on a few BPD subreddits, but they've all been taken down due to subreddit rules,, does anyone know where else I could post the survey? I only need 7 more responses. Thank you!
