Suicide is never ever chosen by an individual. The suicide is committed only when some or the other pain exceeds and one is not capable enough to combat the pain of some particular incident.
Relief: it’s over
If you were closely associated with the victim, probably his misery and trauma may have been very emotional to you. You may have experienced unfair burden, or tired to be associated with very difficult circumstances. This may now be sigh of relief that the victim’s pain is finally over and your burden and concerns have also ended with it. Sometimes even if the end is sad, there can still be relief in it, but now it is colored with guilt. Don’t expect perfection of things, accept the relief and don’t let it turn into guilt.
Accept the things
After the initial shock you will surely feel angry, guilty, and sad of course. These miserable feelings may engulf you all at once, or they may show up after few weeks, months or even years. You may cope up with them well in the beginning only to have them come back for no good reason. These feelings of hopelessness and helplessness will eventually go away. Try to accept what has happened. Your feelings are normal, healthy and a part of the recovery process.
Time will heal everything
There is absolutely nothing in this world which does not heal with time and surely your pain and misery will also fade away. There will be times, however, when these feelings will show up very strongly. Vacations or some special occasions, may bring back your sadness. In particular, during the first year, you will have to decide if you want to uphold activities you shared with the victim or if you want to just cease them in order to feel better. Surely you won’t forget but eventually you will be able to cope up with the passage of time.
