I started getting high to lower my depression and make me happy but...
What happened when you started getting high?
It did make me feel good for a while but after a few weeks I started to feel like shit
It's good to acknowledge your mental health issues. If self-medicating didn't work for you, it might be best to talk to a therapist. They should be able to help you develop coping skills for your depression.
Nah I have too much on my plate right now and I don't have time to see a therapist.
You need to make time. It is important for your health to address it and seek treatment.
