PLEASE HELP!!!!!!!

as

Last January of 2018 I was sick with double pneumonia and the flu. I was only 17 and a senior in high school. I was on life support, and was nearly taking off, while me and my boyfriend had been together for roughly three months. I have had several times where I was readmitted for pneumonia and all kinds of viruses. Me and him have been together for almost a year and a half now. About 2 months ago, I was going to surprise my boyfriend with concert tickets. I realized I couldn't pay online myself, so I asked him to put them on his card and let me pay him cash back. I had picked seats that were reasonably priced, what I could afford. When he went to buy the tickets online, he didn't bother to tell me that he didn't like the seats I picked, so instead of me paying $50 for our tickets, I am now having to pay $125 to ONE ticket, over $200 am Inow having to pay. I felt like, since he didn't tell me he picked better seats, that were more expensive, he was ungrateful. I got sick Sunday night or early Monday morning. I had chills and sweats, bad back pain, major headaches, and a fever of almost 102. I went to the doctor Monday morning, I tested negative for the flu, but they gave me a one-day medication. I felt great yesterday, and my fever was gone last night around 6 p.m. I told my boyfriend that I still wanted to go to the concert this Saturday. Although, this morning I woke up feeling just about how did the first day. I have talked to my boyfriend about the tickets, and he wants to take a so called friend with my ticket. I had already paid him $25 of the more expensive tickets. I don't know if I should just let my boyfriend go with this guy, because he is a bad influence, unappreciative, and only talks to my boyfriend whenever he needs something. What should I do? I don't want to be that type of girlfriend to just tell my man not to go because I can't go, but this was supposed to be OUR trip. I called my boyfriend today at work, crying, and told him my fever was back up. He just acted like he couldn't care less and acted like he was still going to take his so-called friend. I just think it is very rude to take someone else in my place, for OUR trip, and even buy more expensive tickets without asking if I could pay for them.

**I also have brochtiectisis, so my lungs are still VERY VERY sick from over a year ago, and part of my lungs that fight viruses arent working correctly, so the chances of having the flu or any type of virus could send me back to the hospital and/or kill me**

I want him to be here for me, because I couldn't need him more than in a time like this where I'm afraid I'm very sick. When I was sick last year, he only saw me ONE TIME the whole 2 months I was admitted, so if something happens and I'm admitted again, what if he's at the concert, not answering calls from my mom to rell him I'm very ill again?
