I (23M) was abused by my sibling (21M) and ex-girlfriend (21F), I don’t know what to do.

Trigger warning, because the topic includes sexual assault and suicide. Please read with caution if these topics are difficult for you.

This is a throwaway account. I (23M at the time) was drugged with LSD by my younger brother (21M) and ex-girlfriend (21F), during which they used me in my drugged state to sexually take advantage of me. I have horrible memories of the events, bits and pieces, and I’ve filed a report with the police.

Since this happened they have used the narrative that I’m unstable, or rather “delusional”, which has made finding proper mental health treatment and care difficult. I care more about a sentence for both of them, and hopefully my sibling learns a lesson about lying and hurting family. It’s a really fucked up situation, and I’m scared for my safety (I’ve gotten restraining orders against both and live with my parents right now) and I’m concerned with the possibility that I can’t prove this in court. Partially because I think their actions warrant jail time, but also because I’m concerned for the safety for the rest of my family or others who associate with them. I don’t know what to do, who to trust, or how to prove this. It’s been far long enough since the incident that any drug test wouldn’t show positive for anything I was dosed with. I don’t know what to do but I can’t keep living like this. I suppose it’s relevant to mention I’ve had a suicide attempt since that night. Please, any advice is helpful. How do I deal with this properly, besides the report I’ve already made and the restraining orders?

Edit: Sorry for mistakes in my grammar/spelling, I am not very stable currently.
