prescribed meds for anxiety. buspar and wellbutrin any thoughts?

Ive been really struggling lately in life. I'm about 39, married with no kiddos although we wanted a family. We are both diagnosed with an infertility issue and for the last year I've been a wreck because there is no "fix" we can afford. (25k per IVF attempt and it might take 3-6 tries?!) Anyhow we are going to try IUI, IF the dear hubbys issue is somewhat better in July. We keep having delays and its making things worse. It doesn't help that I have PTSD from my time in the fire service AND in the small office where I work are annoyed with me because I'm an "outsider" and an odd duck. I went to a new Dr (mine retired after 38 years) and he suggested I try meds. 15 years ago I was on about every depression med in the book and all had poor results. About 10 years ago we tried buspar and I didn't react well. The new Dr seems to think the combo in low doses will have different results. I'm not so sure, but am willing to try anything to get my life back. The anxiety has made EVERYTHING harder. My daily life is being disrupted by the anxious feelings, crying spells and overwhelming feeling of just being fearful. I'm just not sure about the meds. I'm very distrusting of meds for issues like this because of bad experience in the past.
Anyone have any thoughts? Anyone ever had a good experience out of this combo?
