Do symptoms like hallucinations, seeing people, and smelling odd scents point towards depression or schizophrenia?

Hello doctor,

I am 23-year-old female, I feel I am struggling with my mental health. I not been diagnosed with anything but runs in my family from depression to schizophrenia. But notice lot changes last few months. I do not feel as chatty or want to interact with people. Feel to much for me cope with. Definitely develop anxiety which I have fear doing things be simple wee things I freak out. But the last few weeks started hallucinations again seeing people smelling odd scents. Hearing people shout but no one was there. I had this in past years and feel the same episode I am having now. I do cannabis but I know this is not a problem cause I am only a social smoker and use it for no longer than a year using it. Pervious episodes happen when younger too and did take any medication or drugs. I now stop this cause feared was the problem but has not stopped. Scared talk to someone last time to explain they said straight-up depression saw a doctor since I think more than that. I do tend to forget reality and I have been confused and mixed up if it is real or not if something happened. Just now I am fully exhausted even though I sleep and eat well. I have lost a lot of weight as well. I genuinely do not feel myself anymore.
