I want to make my suicidal thoughts go away?

I've been diagnosed with bipolar disorder. I am 22 years old, I've been on several different psych meds. The ones I'm on now are giving me dizzy spells really bad. I have an appointment with my regular physician tomorrow; I'll ask her to prescribe a different medication. My psychiatrist and my therapist are both free through my college, but I can't go there for another month. I'm living an hour and a half or more from almost everyone I love and I don't have the money or functioning car to visit anyone. I miss my fianc�; he never has time to talk to me. He's taking summer classes and is in class all day every day from Monday-Thursday. On weekends his parents often take him to Canada or camping where he has no cell service and can't get a hold of me. I know things will get better when I go back to school, but until then I just want to die. I'm so lonely all the time; everyone is too busy to talk to me. I just want the pain to go away. I know life is worth living; but, I just want to fall asleep and wake up when I'm not some waste of oxygen.
