No libido during stressful family situation?

Hi I will make this very quick, I’m 20F, dating 20M for over a year. I have recently been in a VERY difficult family situation (parents divorcing, fighting over custody of my brother, my abusive mom threatening to take him to her home country, all while I’m in a different country as well for my studies lol) and I have been EXTREMELY stressed, like pit in stomach, agitated sleep, rashes on body stressed. I also noticed my libido has been inexistant since my luteal phase and I’m now about to start ovulating. The few times my boyfriend initiated, or even I, when I felt a little like it, I was immediately overwhelmed and uneasy and had to stop everything. I cried pretty much each time because I felt guilty lol, and he was super reassuring, telling me to not worry at all. We also touch each other in a non sexual way a lot, but at the same time, this situation makes me feel so unsexy, I feel like I’m not enough, or even question if I’m attracted to him, which I am. But I don’t know, this is messing up with my head, I’m fine masturbating but I just can’t have sex right now?? Has anyone experienced this? Is it the stress? Any advice on how to overcome this? Thank you in advance
