Miserable day

Today's been shit. I feel a rant coming on. It's the first day I've really felt homesick, for my friends and my family. When I got the sim card yesterday I really wanted to call my mum and one particular friend, but it still isn't working now. Jussi gave me his phone to speak to my mum. I haven't lived within 200 miles of her for more than 3 years now, but we usually speak every week or so, so I've missed talking to her. As it's so expensive the phone call was short anyway.
I wish I could meet someone familiar or go somewhere where I know exactly what I'm doing, but everything's alien to me. Jussi's friends have all been very nice to me and made me feel welcome, but they're not MY friends. I completely understand how he felt in England when he wanted to have his own friends, not just rely on mine.
I don't think Jussi realises that going to shops etc still makes me feel quite uncomfortable and I'd appreciate some back up. I don't think he considered how much he would need to help me before we came here. It's hardly as if I want to feel like a child all the time. Of course I want some independence. I do try, but I'm scared and I'm shy. At least when he came to England he could already communicate with everyone; I think he's forgotten what it was like to be in a strange country where everything is new and confusing.
He got a job today, which is great, obviously, but he seems to think I won't be able to cope once he has that taking up so much of his time. Now he's put doubts in my mind, even though I had no concerns beforehand. I'm now trying to make the point to him that I am capable of doing things, even though I'm anxious. I've really been dragged down today; I feel like absolute shit.
I would hate to leave Turku, and I really don't want to quit and be a failure. It seems like no one, including myself, has much faith in my capabilities. I have to go to the police station tomorrow to sort out my social security, and I told Jussi I'd go on my own to prove a point, but I'm absolutely terrified. I'm not even sure what I'm so scared of, apart from the unknown. I don't think that I'm being unreasonable to expect his help in his country. He certainly expected mine in England.
I really hope that things feel different tomorrow, that my sim card works and that I can actually speak to English people. Elisa (the phone network) won't allow you to take out a contract unless you've lived in Finland for at least two years, so Jussi had to do it for me and is lauding the cost of international calls over me a bit. I don't know why it didn't occur to him yesterday that I'd be making international calls - who the hell am I gonna call in Finland? He knows I'll be giving him the money for everything, so surely it's my problem. As I have no money and he's complaining about the phone it's just another thing to wind me up and upset me. I really want tomorrow to be a better day because I'm so miserable and fed up now. This has been the worst day since I got here.
