Are there medications to counter these feelings of despair?

Yes but also explore. These feelings in psychotherapy. As to medication, meet with a psychiatrist and have them evaluate you and decide whether an antidepressant is what's needed or what. Despair usually spells depression; but we are such individual creatures and we express ourselves in such unique ways that ur best bet is to discuss ur feelings in detail with a psychiatrist & see what he/she recommend for you.
