Indeed I do remember you from the depression forum. I'm sorry to hear that your symptoms aren't improving. I really recommend you see a doctor soon to get some relief. Especially if you believe you are bipolar. Depression goes on and on and doesn't go away on its own, most of the time, but bipolar will actually worsen if not treated. If you fear that you have bipolar, you really need to see a mental health professional and ask for an evaluation.
You ARE going to get through this, but you need to reach out for some help. It's fantastic that you found us and are reaching out here, but you need to reach out to real people near you who can help you in practical ways as well. If your family is unreliable, look into other sources of support -- the university, friends, free mental health clinics in your town.
Keep us up to date on how your doing and what steps you're taking.
