I am depressed and can't find enjoyment

Well it all started when I broke up with my gf. I am supposed to move to another country and even tho we knew eachother for only a few months we got together nicely. Her best friend kept telling me for months how she couldn't stop thinking about how will I leave and it wasn't any easier to me, that is when I started falling into depression. I became boring and I spoke less to people in general and I realised it too late. I broke up with my gf because we started seeing eachother less and less and our chats became boring Q&A, and it felt weird and all. It broke me and I needed some time to recover and now after 3 weeks I don't feel any emotion towards her but the hole inside me that began forming 2 months ago is still here. I'm not anymore that sorry that I am going, yes all my family and friemds are here but it is for the best and I got over her and still there is a hole. I can't say that I hardly lough but it is significantly less than I do normaly, I don't find joy in anything and what I mean by that is, for an example computers are my passion and I used to spend 1-2 hours daily watching yt videos and learning but now I can't concentrate for more than 10 minutes. Nothing feels fun and the thing is that I don't even feel depressed that much anymore, it's just, I do don't feel anything and I don't know what to do. I hope there is someone who can help me, I would be grateful. Feel free to ask any additional info I will do my best to dig a bit deeper if it is necessary. And yeah, I am 16. Thank you!

I was thinking about it but every time I do I just overthink and get anxious and don't know what to do and to make matters worse I am currently on a vacation with my family and it's really hard not to think about stuff. Till now my plan was to just keep working on myself and you just showed me the way with your reply and put me in the right direction. Thank you very much, you made my day!
