GD I'm a little older than you and trust me, we ALL go through a little "depression" or soul searching. Sometimes you just get tired of the same routine or a situation in your life happens that makes you look at things a TOTALLY different way. Then you start to wonder, am I wasting my life? Could I be happier doing something else, being with someone else?
I'm not sure what your particular issue is but we all have them and it doesn't mean you need meds or any shit like that, just time. Time to figure out what the problem is, if there even is one, and then then what you need or eant to do different. And trust me everyone (most ppl at least) don't like their job(s) and working alot of hours and not doing other activities or hobbies you do enjoy will make your life hell sometimes.
I have my up and downs days (sometimes weeks) and like I said WE ALL DO, just remember it's not the end of the world, things WILL get better... just BE COOL.
P.S. Oh yeah try doing something that makes you happy that you haven't done in a long time due to not being able to cause of work hours or time restraints due to family or GF's. Then use that time to reflect on what exactly it is thats troubling you.
It usually helps me to just get away from everyone and sit back and relax and reflect. i have a park I used to love going to when I was young but never go there anymore cause I don't live by that side of town anymore, but it has a huge hill and you can see the airfield lights and planes taking off and landing from there. I go there and sit on that hill in peace and quiet with a nice big cigar of wacky backy and go to my happy place to reflect.
