Can't be bothered with life, need some tough love

I go through cycles of feeling neutral and then depressed and right now I'm in the depressed phase. I don't even know where to begin because it's taking every bit of energy I have to type right now. I just can't be bothered with anything anymore. I feel so lethargic and numb. My life is ridiculously boring at the moment with it being summer. I stay up until 1am and then sleep until 1pm. Then usually get out of bed at 3pm, sit around and eat way too much food and then I get a shower and go to bed again. It takes me literally 1-2 hours to muster up the strength to get a shower. I usually get up from my desk (I'm on my computer all the time) and go and get my towel and then I come into my room and lie down for ages because just getting the towel has tired me out. I spend all day in my room, I eat alone, etc. I only have 2 friends which I'm grateful for but we are drifting apart. I've made posts like this before when I've been down and people give advice like invite your friends out, etc. So I spent ages convincing myself to ask one of my friends if she wanted to go shopping or something. I had the Facebook message open for around 10 minutes constantly rereading it before I pressed 'send'. This is a friend I've known since I was 2. Then when she said she couldn't it literally tore me apart. She had a valid excuse but it still made me feel so crap and insecure. I'm going in to a third year of college with plans on going to university next September. I had a 'good' (more like neutral, but for me it was relatively good) week a couple of weeks ago and I ordered lots of prospectuses for universities and I applied to some part-time jobs. That time was short and fleeting, though. Now I have ~20 unopened prospectuses and a group interview on Tuesday. The trigger to this depressive phase was the job interview. I just can't do it. Initially I was considering going so I watched loads of Youtube videos on interview tips and stuff but now the thought of it has triggered my depression. I'm so anxious and shy. I don't even want the job I just need money and my parents are trying to force me to get one. I don't know what to do. I'm not comfortable with talking about how I feel to anyone. I've seen my grandfather and father suffer from depression and witnessed them crying and wishing for their life to be over. The feeling that gave me means that I will never let anyone know that I'm not okay. Before when I've felt like this I just 'took it easy'. I let myself go to college and not socialise and then come home and watch films and eat chocolate and have long baths. But everything is happening all at once at the moment. I've got christenings, weddings, dentist appointments, optician appointments, pressure to get a job, an actual scheduled interview, university applications, starting new classes not knowing anyone, etc all in the next few weeks. The idea of getting a job terrifies me. It wouldn't be so bad having a 1 to 1 interview but nowadays they're all group interviews which is my worst fear. I just feel like I'm not ready to face the World and instead I just want to stay in bed all day. Does anyone have any advice? :(
