stressed and worried

My bf recently has been having black outs. Over the last few months weve been in and out of hospital (i always stay over with him when he get put in a ward) and its really hard. I have to be there for him all the time, i have to be there when he takes a bath now cause he has them so often.
I love him so much and I'm scared.
Its two months till he can have a scan of his brain waves to see whats going on but thats still to months of me being his personal carer and then at the end of those two months we still might not know whats happening.
Its just so hard!
I get so scared when I'm not with him, i'm scared he'll have one when I'm not there and fall and hit his head, or he'll have one when walking across the road and get hit.

Thing is I cant be there for him all the time, its just not possible, when I get my licence I'll be able to pick him up and take him to college but untill then I'm gonna be worried all the time.

I dont know what I'm expecting by writing this I just needed to
