My advice is to go talk to your GP "off the record" and explain the situation that you're in. noone should have to live because of anyone else everybody should have the right to feel good, do what they want and have their own life (remember that for when your children grows up).
Anyway, if your GP is not totaly heartless I dont think they'd object to perscribe medication for you without hospitalization (dont admit that you're suicidal, you're not looking for compasison here just help). you could try to get their email and write to them explaining about your situation (thus giveing you time to present the problem and express yourself in a clever way).
take care, best of luck.
