I totally get that.  When I was a teenager in high school I had some thoughts that really depressed me.  When I went to college those thoughts went away and I became depressed about something else.  After graduating and getting a job and working second shift, those negative thoughts and emotions went away for the most part for a couple of years.  I thought wow, those thoughts don't even phase me anymore but I still had a completely different thought in the back of my mind about something that I thought of everyday but it did not depress me.  Shift to a couple years later, I started working on first shift and later on in the winter time I started riving to work in the dark and going to a workplace with no windows in my area.  Then leave, get a short amount of light and then darkness would come.  Somehow, I was finally able to battle of that thought that I had and not long after that the thoughts in high school started coming back with the emotions one day at work.  I almost had a panic attack.  I thought they were long gone.
I started taking an anti-depressant and klonopin.  Before the anti-depressant kicked in the klonopin did.  It was amazing at first.  The thoughts would come into my head and cause a brief second of anxiety and then disipate.  I have never had that happen before.  I was able to free myself of all the focusing on negative thoughts and emotions for the first time since I was a teenager..  Unfortunately, the klonopin my me sleepy at work and later when the anti-depressant kicked in I started having intestinal problems and apathy.  Years was spend going upend down that roller coaster because now apathy had become the thing I wanted to get rid of.  I messed around trying to get off anti-depressants which is very hard.  I was able to get off them for 1 month and felt great.  Then I got "trigged" again and started panicing about those high school thoughts again.  Unbelievable.  It was at the time that I took a lot of supplements and doubled my anti-depressant dosage so it would "kick in faster".  That is when I got tinnitus.
I'll skip to right now as that was years ago.  What I believe now is that one of the reasons I had emotional problems was due to bad sleep hygine and not enough daylight in the morning and afternoon.  I would take afternoon naps. My circadian rhythm was off as my hours in college and first shift became days where I would wake up very early with lower light levels or none and then on the weekends sleep in late.  I was warned later not to do that by a doctor.  He said it would be very bad for my emotions.  I did not want to listen to him as I enjoyed staying up on the weekends and sleeping in.  In the past couple of years I have had two "sections" of stability.  The first lasted 3 weeks.
My emotions were so stable that I did an experiment.  I listened to the same song every day several times a day.  Normally, I would tire of the same song after a while.  This time I did not.  I had the same emotions each time it played.  How I did that was taking melatonin and a small amount of klonopin at the same time and sleeping the same times on the weekdays and the weekends.  (There were some other things I did to to finally get there though like drinking a lot of water each day and exercising).  Then I started taking a supplement that threw me completely off and I couldn't achieve the stability again due to the T bothering me.
Fast forward to the next year.  I had great stability again for 1 month.  I took melatonin, a small amount of klonopin and magnesium at night and had the same sleep schedule.  I also took Lamictal in the morning.  It went great for a month and my T was lowered after morning.  Again, I did something stupid by stopping the melatonin and magnesium and woke up one day with loud T that wouldn't lower.  Since then my emotions and T have been very erratic.  Lowering the klonopin that I was on which I really want to stop, but the withdrawal also added some dark depressing thoughts that I never had before.  Lately, I have tried to start sleeping at 12 a.m. to 8 p.m. on a regular basis.  It felt kind of weird at first but last night I started drinking a lot of water and I guess the peacefulness of the night calmed me and I felt better.
My T hasn't bothered me much the past couple of days because of the sleep stability but also that I have some hope about my T being lowered more consistently.  I put together this info after researching and trying to anylzye and make since of a journal I took for a few months last year.  Unfortunately, it wasn't as detailed as I needed it to be even though it had a lot of details!  I had to piece together what I think may be what's going on with me.

It's crazy how we can solve a problem and then later focus on another one.  I do think however, it is much easier to get over problems when one is mentally, physically, and spiritually healthy.  That is what I am working on now.  I hope you feel better asap.
