Oh my, I have felt like that once in my life. Counseling and medications was my way out. I was diagnosed with Bipolar 2 Disorder, also known as Bipolar Depression. Since then, my medications and counseling really helped me. Of course, I will have to stay on meds forever, but through counseling I have learned how to handle things a lot better and get on with my life.
The sooner you get counseling the better. I'm a much better person. I have been going through a lot the past couple months, and I just received some even worse news (on my forum post) and I reached out to others to learn how to cope, and now I'm learning ways to do so. It takes a lot, but it is helpful dealing with issues in your life.
You'll be okay

I promise!
