Antidepressants (Wellbutrin)

An
Ok, I started my antidepressants Thursday, anyway I've been experiencing suicidal thoughts pretty bad, and worsened depression, along with insomnia. 
My doctors office is closed today (Damn Holiday!) anyway, there is no after hours #... which they need! 
My husband wants me to quite taking it. But I know it could take up to 4 weeks for it to settle down and start working, I know it can even take longer. 
Has anyone ever experienced this and eventually it wears off? I plan on calling my doctor again tomorrow and seeing what to do but I'm nervous today to take it. This sucks. I'm debating on Fb messaging my therapist. (My depression was so bad last night that I looked her up and debated on messagaing her) 
But thing is, she's just the therapist, I don't get my prescription from her, she's just the woman I speak with.
