Am I overthinking things?

[pawnshopblues]

Okay so I don't really know where to begin.I'm 15 years old and my life pretty much *****.I've been noticing some changes over the past year but I don't really know how to interpret them.
Firstly, I never eat anymore.I don't think I have an eating disorder I would need to have a poor image of myself and I don't really.I don't care about what I weight.Yeah, i do feel ugly and fat sometimes but it passes.I just never get hungry anymore or thirsty.It's like a numbness I have.When I do eat it's because I know I have to so I just eat a chocolate bar or have a cup of tea.
There are so many that changed like my awareness in school.Sometimes I'm really motivated to do my work and then the next it's an off day so I fail a test or forget my homework.The teachers think I'm lazy because they know I can do the work I'm just not trying but I'm trying to do my best my body just won't let me.When they shout at me it makes me think that maybe there is something wrong with me that I can't perform a simple task.I used to enjoy English but my skills are lacking cause I can't think of how to compose sentences anymore.She says it's disorganised and it doesn't make sense but I don't know how to fix it.
My mum and I got in the worst argument a few months ago so I haven't gone home to her.I live at my dad's house but he's never home so I'm usually by myself all day.You would think I would be able to do a simple task like cleaning the dishes in the space of 15 hours but no.
I don't sleep anymore, I don't feel tired for example it's 3:14 am and I'll probably sleep a total of 3 hours but I'll lie in bed all day and walk about in my pj's.Then there will be days where I can't physically move out of bed so I just lay there and I could probably sleep more than 16 hours straight but that's my record so far.
Everything I used to enjoy seems stupid now music, work and even photography.Music is probably one of the biggest things to lose interest in because I absolutely loved collecting vinyl and playing the guitars and stuff like that.I've given up on a lot of my friends too I just can't keep up.
I rarely shower now which is really gross I know.When I do shower it's brief I don't even shave or anything.I used to get my hair done a lot but now I don't care, to be honest.
When I'm out in public I don't talk to anyone or me talk too much to my friends which are down to two of.I don't even cry anymore, I don't laugh I don't have any expressions.
when I'm having a conversation I am never able to stick to the one topic I have to talk about something else because it popped into my head.

Every single thing you've described I have been through as well. The worst is probably not being able to eat because you lose all energy and motivation and basically feel sick. My best advice would be to see a professional, at least see a therapist. For most people, highschool is hard. Most adults will tell you that after you graduate, things will start to get easier. I personally know someone that had severe anxiety and depression throughout high school and now she's in college with barely any problems. Since you're still young and have a few more years to go, try to seek help to get you through. Also, when you are unable to eat it's helpful to drink something like a protein shake or an Ensure. It gets something in your stomach and you don't have to chew. Try to do activities that you know will make you happy (if any). I used to love drawing, watching anime and playing video games. Now the only thing I find enjoyable is going to the mall and buying a ton of new clothes that I'll probably never wear. I know that sounds ridiculous, but when you're suffering with depression, anything that could make you happy helps. If you ever need someone to talk to or discuss this further, feel free to message me. I'm not an expert but sometimes it helps to have someone to talk to.

I believe you should talk to someone, like a therapist. To vent or to discover what's going on.
