I start seeing psychologist mid April. I feel as though I am in a fog, what can I do, now, so that I don't slip further?

I have people around me, but, I feel all alone. I don’t want to burden my girlfriend, as far as being the sole one who gives me emotional support, and I can’t rely on my family. I feel numb, empty and tired. I am having a hard time getting excited about things. Depression? Yes. I am not myself.

I start with counselling soon. In the meantime, what can I do?

Help.
