I don’t know what to do

I was put on medication to treat my depression but I feel like it makes it worse. I stopped taking the medication and I still felt awful. I don’t know what to do. I’m a 13 year old girl and I feel like no one really takes depression for teens so seriously because they think we’re doing it for attention, but I genuinely don’t want to be here. The only thing keeping me here is the thought of hurting my sister. I have cut and I was going to resort to it again, and yes I’m going to a therapist.

I took it for like 2 months maybe and it helped but then it felt like nothing moved
