I have be in for 22 years. At about the 20 year mark I found my self less motivated and more stressed and slight anxiety in stressful situations. I think it’s pretty common at about 20 years. I work for a department with about 600 sworn officers. A few months ago we had a very good officer kill himself. After the funeral another officer went home and did the same thing. I worked with both of them and it really hit me hard. When a brother does it you turn it over and over in you head if you could have done something to prevent it. Of course I couldn’t have but it swims around in my head.
I served in the Navy also and see way to many vets do it also. Why the increase; I have no idea. I lean towards the anti-depressants.
I can retire in two years but am almost reluctant to do so. I have seen a lot of good officers die soon after retirement after crawling into the bottle. I pray Trump gets reelected so when I retire I can drink more liberal tears than beer!
Try some volunteering in retirement. Better to keep your focus a bit more outward than inward if you know what I mean. In this circumstance boredom can literally kill you. You don’t have to make it a full time thing. Start looking for what to do now so you can engage it right away if need be.
