What about subleasing it? Officially, having notified the regie. The defaut position under Swiss law in my general understanding is that sublease is allowed subject to receiving the authorisation by the regie/landlord, which authorisation cannot be refused unless [3 types of situations one of which is charging abusive rent but if you only sublease for the exact same amount you are paying or a little bit more, it is not considered as abusive and it must be approved by the regie]
Here is a website I have recently stumbled upon which explains things
also the famous Art 262 of the Swiss Code of Obligations can be found online in English at https://www.admin.ch/opc/en/classified-compilation/19110009/index.html#a262
Of course, check your contract first to see what specific provisions it contains in relation to sub-letting but I doubt it that it would say anything that is contrary to the law...
I have personally recently had a consultation with Asloca about subletting my flat for a period of time because of a change in circumstances and not being able to be there and Asloca lawyer basically confirmed that, as long as I follow the rules, seek authorisation, disclose the terms of the sublease, do not ask for unreasonably high rent, the regie is not entitled to say no. There may be some tension with respect to how much you want to charge if you decide to sublease. My formula that I have run past Asloca and that they said fine to is as follows: my flat came unfurnished, I have furnished it and am, paying outgoings on it, too, such as electricity, internet, other things, so I am going to take what I am paying to the regie and add all my actual monthly outgoings (electricity, wifi, billag) plus i can add up to 10% by way of compensation for furniture. And that should be considered as a reasonable price, according to Asloca
Don't know if this helps, but hopefully it does, although this stream of consciousness is not very well structured. I hope you find a good solution and a way out of this!
