im experiencing depression and anxiety while my partner is in hospital for mental health

My partner admitted herself to hospital with my support as we understood she was not doing very well mentally. She was very sick, experiencing delusions that fixated on me and the relationship. She had been misdiagnosed with bipolar and her medication was not working. She is now being treated for OCD and is on new medication. She has been in hospital for just under one week and is staying for another week as an inpatient.

Over the last month before hospital, she became very emotionally turbulent and her behaviours were volatile. We live together in a share house, so I didn't have any space to escape to my own. Due to my partner's delusions and paranoia (which I now understand was the obsessive compulsions), she emotionally abused me.

I am struggling to accept this idea and I feel guilty for labelling myself as a victim of emotional abuse, and her an abuser as I know she was not herself during those times.

My Partner acknowledges the behaviour as emotional abuse and is working very hard on herself and is learning new tools to cope with emotion management etc.

I think now that everything has started to settle, she is in hospital and we are having some healthy space apart, my body is able to begin processing.

I have been feeling waves of depression and anxiety within the same afternoon, and I feel anxiously attached to my partner who I don't feel I can lean on at the moment as she has her own mental health to focus on. I feel guilt, worry, stress that I might have a form of ptsd from what happened. Is it possible that for my body to regulate I am experiencing a multitude of emotions? My brain feels very foggy and I can't think about what thoughts are provoking these feelings, although writing this post has very much helped.
