Insight: Grief is difficult to navigate. First and foremost, allow yourself the space to grieve. Even if it is a few minutes each day. If you hold these deep emotions in it only causes more pain in the long run. Emotions that are bottled up only fester, it is important to express these emotions.
Secondly, everyone grieves differently. Something that may help someone else cope may not help you at all. One thing I have found helpful when dealing with my own grief is journaling. It enables me to get out my emotions in a safe environment. Best thing would be to try a few things and see what works for you. Some people write letters to the lost loved one, some people talk to them verbally when they are alone as if they are there.
Lastly, rely on God's strength to pull you through, and do not be scared to rely on other people you trust. Another resource is a grief group, everyone in the group is experiencing loss and you may find comfort and tools from others in the group. If you need to vent or just need some comfort these are the best places to go.
I strive to help others by being a safe place for others to ask questions and pose issues they face.
