Were you under the care of a therapist the first time around? If so, make an appointment to go seem him. If you were on meds, you may need them again.
I do understand your fear of everything falling in on you again. No one wants to be in pain and emotional pain can be as bad if not worse than physical pain.

Remember, you made it through the first time. You are strong, you have experience with that monster from before so you have an idea what to expect and how to deal with it.

I hope you feel better soon.
