My relationship might be dead

I've been with my boyfriend for almost three years but I haven't been able to see him because of Covid (we still live in each other's parent's house). So we've been having a year of a long distance relationship and it hasn't been bad, like we love and respect each other. However, I suffer from very bad mental health and I really tried to not get him involved in my issues but it's impossible, I've had pretty bad panic episodes which caused me to harm myself (I'm seeing a doctor and a psychologist right now) but I don't know, college is making me very stressed. After all these episodes we just started pushing each other away, I keep trying to talk to him but he just doesn't, is like he's disappearing. I don't really know what to do anymore.
