I feel like I'm falling behind everyone. How do I actually start to feel okay again?

I don't really know when it started but at some point I just stopped feeling like myself. I look around at people my age and everyone seems to have friends, confidence, a social life, things to look forward to. I feel like I'm missing all of it. My home situation is pretty restrictive and I don't have much freedom to do the normal things most kids my age do which makes the isolation worse. I've been stuck in this pattern where I'm up too late every night, wake up exhausted, and just go through the motions at school. On top of that I've been feeling guilty about not keeping up with things that are important to me. It's all been piling up and I've been keeping it completely to myself because I don't even know how to explain it to anyone. I started thinking about how long I'd actually been feeling this way and realized it had been longer than I'd admitted to myself. I also thought about how many different things were contributing at once and how trying to look at all of them together made everything feel impossible to even start dealing with. The sleep, the isolation, the guilt, the way I felt about myself. None of it existed separately but I'd been treating it like one giant unsolvable thing. I realized I hadn't told anyone how bad it had actually gotten. Not even close to the real version. I'd been so used to acting like things were fine that I didn't even know how to start that conversation. But carrying it completely alone was making every part of it heavier than it needed to be. Talking it through helped me stop looking at everything as one giant problem and start seeing it as separate things that could be dealt with one at a time. We agreed the best next step was two things. First try to shift the late night routine even slightly because the exhaustion was making everything else harder to manage. Second seriously consider talking to a counselor or a trusted adult, not to fix everything at once but just to have someone who actually knew what was going on. I'd been invisible with this for too long and that was the one thing I could actually change right now.
