Help feeling connection again

Hello, I apologize if this does not fit with the subreddit and I understand if others need help first.

My life feels empty and meaningless. As if every facet of my being: home life, work life, and social life are all just things I have to survive so I can wake up tomorrow. I have no grand guiding vision or want besides to feel happy again. I have recently made meaningful steps to improve my life, but it still feels empty. Sometimes I feel on top of the world and other times buried beneath it. I look back to when I was happy and find a major thing I now lack: connection.

I now feel like every relation in my life is hollow and any attempt I do at making them meaningful is met with disinterest. I have maybe one or two people who text me without me texting first. I don't see anyone else that often either. Even while I work customer service, I am not really expected to get into intimate conversation while serving their food. I cannot relate to my coworkers as they talk about experiences I yearn for and cannot have. I try to text old friends and am met with conversations where I am asking questions hoping for something deeper, people who seem down to hangout but cancel last minute, or am left on seen. Back in school, I knew a decent chunk of people and could strike up conversation and briefly hang with people. I would tutor people at subjects I excelled at. But it never went outside of school because I had no transportation to meet with anyone. And now I do, but nobody to see and meet as I have since graduated.

I feel so alone and I just need some plan of action to fix it.
