Struggling to Find Motivation Without Cannabis

So I am new here today and I'm not sure how this work as but on this topic I have a question. I have bad depression like symptoms with some anxiety and anger on bad days mostly at myself. I thought about trying cannabis and well I actually did try it once but. I even think it could help if I could function while using it. But I can't do anything. I mean anything but sleep. How do u fix that and no I'm not joking. I understand it would be funny to those who use it and can move on with the day. I just want to do the same.
