im so useless, even tho i try my best to help i fuck it up everytime

I have been feeling so stupid. I thought I could work in a long distance relationship. After feeling neglected for months I finally told her how I felt, and that something needed to change cause I can't keep crying over this. Jokes on me, cause yesterday she was barely online at all and I spent the whole morning crying anyway. Today is a new day where she hasn't texted me during her day cycle, and again, I am spending the morning crying. I worry that now that I've expressed a need, she'll dump me. I worry about that every time I express a need to anyone. I just want to be loved, I want to have my emotional needs met. I need to feel like someone cares if I'm down or if I haven't been eating, if I've been waking up to nightmares for three nights in a row. It always feels like a sin to need comfort, worst of all to ask for it. Like a sin to voice a need. I love her, and I need her. I need her to care like I care for her. Am I so unlovable I can't ever have that?

Highschool is hard. Growing up I've never had a guy ask me out or even spark interest in me, but it was completely different for everyone else around me. All of my friends, peers, and classmates had or have partners and I really feel like im missing out. Im tuned in with socializing, and I do make attempts at putting myself out there, but it feels hopeless almost every time. It might sound like being desperate to some, but overall its just a fear that im behind or im just hard to love. I dont need male validation at all, but relationships have been made to be so important in highschool. Because of that, its always been one of my highest priorities, and im trying my best on figuring out how to prioritize myself first. Any advice for the following and coping with FOMO?
