Anyone else feels like this?

I feel so alone. For as long as I can remember I can never feel truly happy. I am constantly tired and sad for like 3 years now, even though i am so young. Just a state of being tired and upset. I dont know how to “fill the void“ feels like i have tried everything. I also don’t feel as if I fit anywhere and that i can never truly bond with someone. I have a boyfriend and I love him with my whole heart but my mood sometimes entirely depends on him. Just don’t know what to do or where to go. I wish I could just stop feeling altogether. Sorry for the vent Lol super emo.
