Girlfriend exaggerated with birthday presents and I feel guilty 😣?

My girlfriend has always lived with her parents for her entire life. No friends no social life. Then... she comes living with me. First boyfriend, first moving in together, first bills to pay. She started working and does 2 jobs to help with the rent. This month I had my birthday and she organised a dinner for the two of us... at home..she had done my favorite dishes and the cake I prefer. Then gave me my presents, a winter parka (I actually needed it, as I was still going around  with a light one), some shirts and pullovers because she wants me to dress not like my style, you know sweatpants and sweatshirts. At the end, she gave me my new fishing boots (she remembered I needed them) and an half price holiday booked for this summer, in turkey. Together. She was so happy giving all this to me and her face was smiling the whole time. I have to be honest I feel really guilty about all this. She spent lots of money on me while I was complaining about being alone on sunday (she works on sunday in purpose to get a better pay) and another time she went as a translator for a process in a far town, like 3 hours away on public transport I was upset the whole time why she accepted. She later told me she earned a lot even just that day. And she said she's happy when I am happy. I don't know what to say. Thank you will never be enough. I was raised by a foster family and I never had these kind of treatment. I saw their children being spoilrd and me being treated like I didnt belong there
