I would very definitely talk to your M.D. about it on Monday morning and avoid putting yourself in dangerous situations until then. Suicidal urges are a side-effect of some psych meds. Whatever you're doing be careful to take your meds absolutely steadily and only change anything together with your M.D.

I know it sounds silly, but people are really bad about taking meds every single day without fail. Unless you have one of those pill organizers (which I really recommend), it's very easy to forget if you've taken something or double take by mistake or suddenly run out of something on the weekend.
