Exhausted

My mood keeps deteriorating with every passing day. My positive attitude too. I'm rarely happy these days. I have mood swings that last days, weeks now. I cry at least once every two days. I'm actively considering dropping out cos I've lost interest in school, in learning. I've lost interest in almost everything tbh. I keep hearing, "You'll be fine, you'll be fine". But, it's not feeling like it. It feels like people just say it so, my mind would think I would be fine. But, in reality, it's not fine, it won't be. No one exactly understands what I feel. Not like I understand either. I have a few friends and they are leaving. The others don't talk to me anymore. It's like I'm there but, no one can see me. They're all probably tired of me and my swings already. I probably caused it. I don't know. I get suicidal thoughts sometimes. I wish for death too. Even have dreams of it. But, it just never seems to happen. I'm tired of everything. Everything. I don't want to feel this way. I'd really appreciate any help I'd get from you😔
