4. Your S.O. loses interest in favorite pasttimes. Watch out for a sudden loss of interest or avoiding activities he/she once enjoyed. This can be indicative of a deep depressive state and could lead to major problems down the road in your relationship.
5. Your S.O. is always tense. Living in a constant state of panic can be very stressful for your significant other. Loud noises or even a car backfiring can set off a panic attack. Over time, this kind of anxiety can lead to health problems that may be irreversible.
These signs are normal (to some extent) right after a tragic event. However, if your loved one exhibits these signs for longer than a month, you should encourage him/her to speak with a health care professional. Seek treatment as soon as possible to be on the safe side. Support groups are also a good idea, especially in the most extreme cases.
