I have no friends

I have had no friends since i was in middle school. I am now 15 years old and I have tried my best to make friends but a lot of the people I meet make excuses to not hang out with me. I tried making online friends and I met a lot of creeps and people who just ghost me after a couple of days. I have been since 7th grade doing homeschooling and it’s definitely a little worse than doing in-person school. I just stay in my house every day and I don’t even do school work because of my concentration issues. Idk how there is almost 1,000 people in my school but not even one person is my friend.
