Somebody help me, please?

Have you seen a doctor? If not, do it. It could be panic attacks, or some other form of an anxiety disorder. It could be postpartum depression. It could be a neurological disorder, hyperthyroidism or a number of other medical illness that would have to be ruled out long before you could be diagnosed with any mental health problem. If you don't have medical insurance, I am sure there are free medical services available in your area, your just need to know where to look. Start out by contacting the department of health and human services office in your area. It may be under a number of different names, DSHS, DHS, DHHS, or a number of others. But the symptoms you are describing a very general and could be a number fo things. First things first, you need to be seen by a medical doctor.
