Advice for Dealing with Multiple Mental Health Issues

Finding a regular therapist to see would probably be the best thing. If that's something you're unable to do at the time then I would personally from my own experiences say making yourself a routine to stick to and following it the best you can would be a good step. Even if it's an incredibly small routine like wake up and eat breakfast. A great app for that is Finch, I use it a lot for their goal setting system. For ocd with psychotic features though I'd stress that you should really find a regular therapist to see and see what they have to say.
