It always help to talk things over so yes, call the helpline.
Also when you feel able, post again with more details about your situation. TP has been immense help to me when I have felt overwhelmed, incredibly sad, like I was making no difference, when I was sleep deprived and just did not know what to do next. After a few hours, sometimes only a few minutes a load of responses would appear to my post and it helped to know that somewhere, out there, people who had experienced or were experiencing the same thing and giving me support, advice and encouragement. We are all listening.
