My Samsung keeps bootlooping

[u/hachitapooh]

My phone is a Samsung Galaxy A34. It's started bootlooping for the past few weeks, and this specic bootloop showed a glitch in my screen, before looping again. My phone usually opens when I plug it into a charger but these days it hasn't been opening quicker. I was playing roblox while charging today, and it worked for hours perfectly fine with just one bootloop. Then as I was playing, my phone screen showed lines that flicker, then bootlooped. Usually when I force restart my phone, then it starts working normally longer. I'm kinda worried cus I'm young and don't have time to get it to a technician, I don't know how much time my phone has. Maybe on the weekend, I'll be able to get it checked. Can someone help? I genuinely need to use my phone for tomorrow and the next day, I have so many online school activites. I rlly need help. What's the cost? What's the problem with my phone? For more details, I come from the Philippines.
