Still worried

My aunt is finally home from the hospital and I'm so glad. I'm trying to talk to her every day and keep in touch but it's difficult. Gabe had been feeling better but is still sick. He still doesn't have his normal strength or energy and he's been sick for a couple of weeks now. I need to just take his stubborn ass to the doctor; I should have days and days ago. I fear this has been too much for him and eventually all of this will catch up with him and I won't be enough to help him get back together. I marvel that I haven't gotten sick; and I'm grateful for that. Honestly that's a consistent worry in my head; that I'm not enough for anyone and am letting everyone down. I don't have many people I truly can't live without and the thought of losing any one of them hurts unbearably. I fear for my mom and grandma if anything should happen to my aunt and myself if anything should happen to Gabe. He actually asked me to bring him some medicine at work and I should have just told him to come to the doctor with me. I know he doesn't like to complain but he told me he wasn't feeling well; that says enough, he needs help that I can't give. I'll happily take care of him as much as I can but I'm not a doctor. I at least want to know specifically what he has. I lost my dad and grandpa as suddenly as he lost his brother; I'll be God damned if I'm going to lose him. There was nothing I could do in the first two cases; not so here. He knows I worry and overthink but he needs to worry less about my feelings and more about his wellbeing. Being stressed is better than mourning, you know? I guess that's enough for now.
