Is it unreasonable to ask my girlfriend to make our relationship more of a priority?

I have been in a LDR for over 6 months and I will be seeing her in just a couple of weeks. Things had been going very well for a while, but I am starting to feel neglected by her. She lives in Colombia and has a 5-year-old son, and just got a new job with health insurance. A week into her new job she was very sick and was hospitalized for anemia and a kidney infection. I had no idea until one of her friends contacted me 3 days later after seeing my messages because her Facebook messenger was open on her phone. Given that she wasn't paid yet for her new job, she had her friend sell her phone so she could pay rent. I got her this phone as a gift because her old phone was horrible with video calls. Her friend visited her in the hospital and let her use her phone so we could talk and her friend did that until she was discharged. She was discharged 3 days ago and I haven't heard from her since even though I helped pay for her son's monthly tuition ($75) and her hospital bill ($100) since she won't be paid for a couple of weeks. She was discharged from the hospital 3 days ago and we haven't talked since, she hasn't connected to social media, and I have no way of communicating.

Here is what bothers me: She didn't think to tell me that she was in the hospital or ask someone to contact me to tell me. Her friend just happened to have her social media account logged-in on her phone and noticed that I have been trying to get in touch with her. She sold a gift that I gave her for the specific purpose of being able to communicate in a LDR, now we have no way to communicate and she hasn't tried to use a friends phone to contact me.

I don't expect to be the first person she contacts, but I guess my expectation is that I am enough priority in her life where she though about telling me. I also understand that she has to pay rent, but she sold my gift and our only way to communicate and hasn't tried to contact me since which again makes me feel unimportant.
