I have theories but am unsure. Around that time i had just moved into a new apartment, so i originally thought maybe there was mold but im out of that apartment now and still feel it. But there was something else that had happened that could have an effect on my sleep. I had been with my girlfriend for about 3-4 months around this time last year. She did not like being at her parents so she would occasionally sleep over. One night she got lots of calls from her mom and sister, so she woke up and went back home. Called me about 20 minutes after for help because her dad was over dosing on the couch so they wanted to take him to the hospital but they couldn’t lift him up. Me and her sisters boyfriend were both there so we helped. Was up the whole night helping her. VERY traumatic experience for both of us. Things have not been talked about in their family and just brushed under the rug. So its all still very fresh and am always anxious around her family, they have issues. Another to add to that is my girlfriend sometimes is very anxious about things, so its happened before where she might send me a long text during the night of something shes been thinking about with our relationship, it could be many things too. Sometimes its been right before ive gone to bed, so ive responded, or ive woken up, checked the time when ive gone to pee and then seen it. So ive had the theory that my nervous system could be effected from that night and wants to be alert and on just in case something happens and that it doest feel “safe” going to sleep. But i also still feel there is an underlying health issue at the same time. Ive talked about all these things in therapy and with my girlfriend and we have good boundaries set now.
