I just want my bestie back

I had a bestfriend and we've been friends for 2-3 years, then one day she started ignoring me and even being a little mean after we finally met, her mom said she became depressed because they became "poor" like girl.. she literally brought new clothes and robux on roblox while she doesnt even play roblox, but i believed it and tried to be understanding, i asked her if she wants to call me but she didnt, then i didnt really bother her for months, today i asked her if she wants to call, she said we can in the afternoon, i didnt really had any other friends other than her so i just wanted to get contact with her again and talk again, she didnt call me in the afternoon so instead i called her, we played roblox because she wanted to, we only played for 20 minutes before she said an excuse that she has a low battery, i said "then put it on the charger" and she said the most lame excuse, she said "my mom doesnt like it when i put it on the charger because i always break the charger", and i said ok... and then she said shes gonna go painting, i was so disappointed she was acting so bad.. faking her happiness for seeing me, and then i saw that shes posting on youtube and has a friend named "esi_vidi", she makes terrible and cringe content but on every video it writes "boro is my bestfriend" and stuff, my bestfriend replaced me with her 🙁 she doesnt like me anymore, i just cant stop thinking that i might be the wrong person or her, im also homeshcooled for years now and its extremely hard for me to socialize but at the same time i dont want to go to school :(
