I believe I can help you with your concern
Please give me a couple minutes to read over your question thoroughly so that I can better assist you
I am so sorry that you exhibiting these symptoms currently, I can understand how this would distress you
It sounds like from your symptoms that you have a depressive disorder that is very serious as you had an impulse to end your life recently. Also binge drinking is a form of self-medicating to help you cope, but in face alcohol is a depressant and actually makes your symptoms worse
I would like to recommend some therapeutic techniques that can help you through this, but I would also like to encourage you to see a therapist as well, so that you have someone to talk to you and have the support of. The best type and most evidence based therapy to help with these symptoms is called Cognitive Behavioral Therapy (CBT). CBT has a premise that your symptoms are caused by negative thoughts, so if we change your thought process to be more positive and objective as well, then your symptoms will lessen.
So this link may help you, it contains a technique I use with patients called a thought record. It will help you keep track of any negative thoughts you have. You put the negative thought on paper, the emotion accompanying, the evidence to support it, and the evidence against it. Then I want you to come up with an alternative thought for the situation (more objective and plausible). This will help you change your way of thinking to be able to think more positive and not automatically go to a negative type of thinking.
In addition, these two worksheets are very good at helping lessen depressive symptoms. It can help you focus on the big picture and the objective/positive thoughts and outcomes.
Also individuals with severe depression have a poor coping mechanism, so this worksheet will help you develop a better coping strategy to manage your symptoms better.
Individuals with a depressive disorder also may have low self-confidence, so this technique will help you replace any self-critical thoughts that you may have with more positive self-beliefs.
I would also like to recommend these two books as well
Now because therapy is a gradual process and takes time to be effective, I would like to recommend some medication that you can ask your Prescribing physician or a psychiatrist about. I think Escitalopram at 10-20mg would be very effective for you as it is a SSRI antidepressant, is fast acting, and has minimal side effects.
Now you really focused on depression and sadness in your question, but you did mention a brief overlay of "hyperactivity," can you describe that in more detail for me. How long does this hyperactivity last for you?
Do you sense that hyperactivity cycles for you between hyperactive and depression?
Well then this does sound like a depressive disorder then. I was concerned there for a minute about the term hyperactivity that you used and wanted to ask those questions as sometimes it could be indicative of Bipolar Disorder, but if you are reacting to environmental stimuli in the way you described then most likely this is a depressive disorder
The techniques and medication should help you greatly with these symptoms
Do you have any questions or concerns?
Well there are natural supplements that can help too, but not as effective as the medication. They are St. Johns Wort and Omega-3 (Fish Oil), so you can try those two natural supplements and pick them up at any local grocery store
Other people like your friends and co-workers, or are you asking how to talk to a therapist about this?
Well with friends you can tell them when you are ready, but you can start by saying that you have started to see a therapist to help with some depressive issues that you have been struggling with for some time. You did not know how to bring it up or if it was "normal" for you to feel this way, but recently you felt that you should see a professional to help with these symptoms.
That can be a good way to start if you wanted to tell your friends
But I would recommend going to therapy first and talking with your therapist on how to tell your friends. Then you both can discuss scenarios on what to tell your friends and what you may not feel comfortable telling them
