I have bipolar disorder. I've had multiple serious rounds of depression. I'll give you the best advice I can. First see a doctor. You may need medication. Second therapy makes a huge difference. Third, if you can, find someone you trust to tell. Support is crucial. If you really feel like you can't talk to anyone, keep posting here. We will support you. Try to get fresh air daily if you can. Take things one step at a time and know that it will be okay. Hugs.
