Loxapine is an antipsychotic
drug and SSRIs are newer antidepressants. There are many other newer antipsychotics these days which are effective with less significant side effects like olanzapine
Acute psychosis consists of episodes of psychosis having onset within 2 weeks and with proper timely treatment, can be treated with short term treatment easily. However long term treatment is required in recurrent cases (as in your case). Schizophrenia
is a chronic illness which requires usually long term treatment, perhaps lifelong.
Complete recovery is possible in cases of acute psychosis whereas in schizophrenia it may or may not occur.
Continue your treatment and have faith in your doctor
