Thanks everyone for your contributions in this thread. It has been very helpful. Thanks DJ/Derek for bumping this thread or I would not have seen it and read it.
I am 35, married, <2 year old daughter. I've been in a senior sales role for over 3.5 years and many factors contributed to me not being happy at work that progressively worsened for me (at least how I viewed the things happening to me at work). I did not like my line manager for a period (until line reporting was changed last year). My assessment is on the sales I bring in but I was handling nearly 70% operations duties.
I did not see a light for career development not know where I would be or what I would do in the future. I work in a time zone that can talk to Australia through to USA EST in one day, the strain of emails from 7AM to 10PM really got to me. Every "holiday" I'm still checking emails.
I work in an office with 4 people where I am the most senior I lacked anyone of a similar level to discuss face to face on issues, strategies or even to joke around with. "Cabin Fever" was the best expression I could locate at the time. I've gone through episodes (hours) of feeling helpless, upset, inadequate, and just felt like ending it all even though I know very well there are people both family and friends who love me dearly. In those episodes it felt overwhelmed and like the walls were caving in.
My language was definitely negative (even in this post). There was a period last year I removed a lot of my friends of social media just kept trying to close in/go into my cave. I thought it would help to be more alone, it didn't.
I discovered BJJ about 7 months ago and in that I've truly discovered an activity that I love and can aspire to be better in. The focus during class (away from my wandering mind) and the cardio release really helped my mood. I felt I cleansed negative energy in the process. I am feel very grateful for finding it and I will invest more time in it.
I have tried to understand everyone's point of view in this thread and have considered the medical and holistic/self help paths. In the last few days:
I downloaded Power of Now on Kindle.
Increased my Vitamin D intake (I am dark skinned).
Ensuring I eat every few hours, I'm type 2 D.
Turn off the phone after 9PM (working towards that being an hour or more earlier). Stop using the phone in a darker room.
Cold Showers (need to try that).
I started entering into a Gratitude journal on Evernote. I figured if I think about what I'm grateful for things will seem happier relatively.
I am considering changing my work environment (starting the process).
I've talked about what I'm going through with a few friends.
Need to get into a more regimented sleep pattern (same time, same number of hours).
Sorry to hear some of the situations you all have gone through. Will work through this for me for the better.
