Medication isn't some magic cure. Suffering isn't always the result of mental disorder. Even if it is, drugs don't sweep it all away. They're imprecise.
Medication can take the edge off mental/emotional pain, which can make things feel more bearable or allow you to feel able to try a new plan to change things. It might be worth it for that. It might not. Only you know, op.
I am sorry things have been so hard for you. Feeling alone in the world is really shit.
The psychologist may still come back to you - these things can unfortunately be slow. Would you feel able to chase up?
If there has been trauma in your life, psychological therapy may help you. It won't fix everything, but it could help your brain process it, help you find practical coping tools, and reduce your pain levels enough for the other practical crappy stuff in your life to feel bearable to face.
Maybe for now it's about only staying in the present moment and trying not to let your mind pull you into the wasteland you're seeing as the future?
If I'm off base, disregard my comments. I don't want to invalidate what you're going through.
