I feel lonely

I have 2 awesome friends, we used to do so much together, call till the end of the day, honestly they were the only people who cheered me up. But recently both of them found new friends and they dont talk to me anymore, when I ask if we could do something they already say that they planned things with their other friends, which leaves me alone. I only have these two friends so I dont have anyone else to approach. Everyday when I get home from school I eat and immediately sleep, I have no motivation for anything anymore, without these 2 specific people my life feels meaningless, its been over a year since ive hung out with anybody. I still chat with them every day but we dont meet anymore, they are my best friends but I think for them I am nothing but a last option. I feel so lonely having no one around me, I tried my best to create new friends but none of them are like me, and this is another thing I struggle with, I am not like usual teenagers, I dont drink, I dont vape or smoke and I dont party, maybe this is the reason why they dont spend time with me anymore? I have tried to talk to them about my loneliness but they told me to find new friends so that I have people with who I can spend time with while they are busy, but yeah, I just cant? it doesnt work for me, plus it feels wrong somehow. Please tell me what I have to do, how do I get their attention back?
