Awww hon, so sorry.

Everyone snaps sometimes. No one is perfect. A note might be nice to repair the relationship, but I don't think it would be necessary.

Most people go through ups and downs dealing with mental health issues. If you felt better before, you can get there again. Just have to get through this hard part. Take it easy on yourself and try to be comfortable. Neck pain affects your whole body and can make you miserable.

So sorry you are dealing with both physical and mental pain. You have to be very strong to do so. Even if you behaved less perfectly than you would have liked, you are still doing the best you can.
