if it is anxiety that is the problem, try things like chamomile tea with honey when you wake up (it is the go-to for sleep), benadryl for insomnia, and maybe.....hmm....melatonin.....
besides that, try deep breathing routines. Animals help too....service dogs are a great idea....that with some breathing techniques should be useful. A Mediterranean diet is supported to help. So is social interaction, so try a church group or something with nice people, don't go to a dive bar for social interaction. Social interaction is not emphasized enough.
Really, have structure, exercise, and the rest I just wrote, and that should help at least some.
But really, really really, you need an antipsychotic.
