How can I get some antidepressants

I've been diagnosed with major depression for the last 6 years but now that i'm skipping class to sleep all day, and pursuing very destructive behaviours, i think in this moment i really need help so i don't continue spiralling. Don't really want to navigate the counselling services. Do i just make an appointment with SHS?

Edit: I will definitely try to look into these resources. I really appreciate all of the information, and as i muster up the energy to get help, i can hopefully work towards a healthier mind.
