Hi Gj!

First: you do have support, here!

Second: you counselor had the right idea, but lacking a method: “I even met a life counsellor and her advice was to focus on being happy.”

Third: Apply Karma, Cause & Effect. In your case it is simple: To experience happiness yourself, find a way to make others happy/content.

Help in an animal shelter or a homeless kitchen. Go to places where you can remove a little of the suffering of other sentient beings and sooner than later that karma comes to fruition for you.

Just do it and you are already on your way up.
