We humans do everything and anything just to gain happiness....be it choosing a field of education, selection of job, traveling etc I understand your need to be in the said relation, I would recommend you to ask yourself​ a simple question....where is this relation taking me....is it giving me happiness, is it helping me grow??? As to dealing with anxiety, more details would be needed to figure out what is troubling you and what kind of a person you are to be able to help you....
