I feel so lost and dejected

I am 26F and a hardcore introvert and somehow from high school to now I just had one person I could call my friend, I dislike and hate 99% of the people I meet and the 1% I like I become so awkward and basically self sabotage. So Like literally just one friend. And she moved across continents around a year and a half ago. We used to text, FaceTime but lately it seems she has no time to talk to me. And off late she doesn’t let me share anything that’s happening with me, as everything that’s happening with me seems boring. I feel so lost and lonely and dejected. I am afraid I’ll never be able to make another friend - ‘real friend’ in this age in life. I feel like crying all the time. What do I do?
