I feel much calmer on meds, I still feel depressed and anxious a lot but it is much more manageable. I also don't hear voices in the night (the voices are often social services saying they are taking my children away.)
Without meds, I'm very irritable. I find it extremely difficult coping with my DC if they're crying for example. I get angry or upset quickly and can't down from it. For example if on my own and I watch a sad film, I'll literally be in floods of tears, in the depths of despair for hours. (If someone is with me they can help calm me down.) I get so anxious leading to isolation and depressed which can lead to self harm and suicidal ideation.
The best thing you could do if I'm all over the place is check I've taken my meds and if not get me to take them and secondly help me do something to calm down like taking deep breaths or a grounding exercise. Lots of validation and support would be much appreciated.
You sound lovely, you're friend is lucky to have you.
