I'm angry and irritable all the time and sometimes cry at night. i have panic disorder and agoraphobia, no friends and don't see family. bipolar??

Sounds terribly sad: Do you see a therapist? Please try to find one you can trust. This may take a long time and be difficult but it's worth it! Bipolar may be there too, but it's not all. Medication for it might get you started but you need to find a human to relate to. Even if you start very safe and slow - it's a nutrient for life. One step at a time. Get a psych eval. Move from there. Best!
