I've been going through a lot lately and have been looking after my mum who is not good, so i've been stressed and not eating and constipated, ?

It's time to take: Care of yourself. Aim for daily exercise, 8 hours of sleep per night & good nutrition with 5 servings of veggies & 4 of fruit per day. Try tai chi, yoga, qi gong, progressive muscle relaxation, deep breathing exercises & meditation. Don't isolate - spend time with friends and stay active. Supportive counseling might also be beneficial. Take care.
