I took a temporary job a few months ago as a research assistant at a large university. While I knew a portion of the job would involve cold-calling potential research participants to try to get them to sign up for studies, it has turned into the majority of the job. So far most people haven't been overly rude to me, but I hate, hate, HATE cold-calling. Hate it. I absolutely wouldn't have taken the job if I had realized how much of this I would have to do, but I didn't ask enough questions during the interview. 

Every day after work I'm just filled with dread and fear about the next day. I don't enjoy the weekends because as soon as I clock out on Friday, I'm already dreading Monday morning. I don't want to quit because I have a patchy resume and I've quit a job quickly due to anxiety before, which really disappointed and upset my parents, whom I'm now living with. I'm also the only one available to go in for the (rare) onsite tasks in my designated research area, so I would be leaving my supervisors/coworkers in a real bind. This is a temporary job until June and I want/need to stick it out until then, but it's been so miserable. I don't even want to do anything after work or on the weekends, I just sit in my bedroom (the same room I work from during the week) and browse the web.  I feel trapped, desperate, and miserable, even though I know a lot of people would appreciate having any job right now. Is there anything I can do to make this better?
