I'm 23 years old and I live in Portugal, next month (September 18) I'm going with my girlfriend to live and work in Switzerland with her family. The mother has a restaurant and we go there to work, It's not guaranteed a big salary but it gives us our own house and food so we don't have to spend anything. She is married to a Swiss. my girlfriend's aunt lives there, also married to a Swiss man.
Neither I nor my girlfriend wanted to go, but for over a year we have been looking for work and have not found anything.The problem is that both she and I have psychological problems. We both have anxieties and depression, among other things.  I have social anxiety, so one of my biggest problems is relating to people... I'm scared to death whenever I'm with my girlfriend's mother or husband.I'm scared to death whenever I'm in someone else's house because I feel uncomfortableI'm scared to death whenever I'm in someone else's house because I feel uncomfortable It's a month away and I already have panic attacks and I'm starting to not sleepIt's a month away and I already have panic attacks and I'm starting to not sleep I'm afraid to embarrass myself, that everyone laughs at me, that they think I'm shit after all... I'm afraid when they speak in French and I don't understand... I know they're not saying anything bad,Much less about me... But my head starts to get stressed and I start to have  having panic attacks.But I need to work and make my living, my parents are poor and have made many sacrifices for me to study so I can be independent with a good life. I want them to stop worrying about me, to let them know I'm okay... But it just puts more pressure and anxiety on me because I'm afraid of failing.
I'm also afraid to leave my parents alone, my mother had a stroke last year and since then my father has taken care of her.... I don't say anything but I know that both also suffer from depression and Anxiety.

I'm afraid of getting there and not being good at work, of thinking I'm not doing anything.... I go because they want my girlfriend to go, not because they want me to go So I feel like I don't belong there and they don't want me there.... They just tolerate me

I don't know if I expressed myself well... More than half of what I wrote I was crying... 

I know I have to go... I just need someone to tell me everything will be fine... Or to give me some advice... I can't talk to my girlfriend about this because she's anxious too and I don't want it to get any worse...I've been having panic attacks every day, and they're getting worse.
