I am so sorry for your loss. Thank you as well for bringing this one up, I've been also suffering for the same condition worst would be last year tho luckily right now I am on the process of recovering

I know that as person who struggle for this type of problem, the first thing we should do is to reach out but that is exactly the problem. While talking to a person who is also been struggling with this(she actually has a worse struggle than I do). The first thing that came up with my mind is that they are not sharing it because they can't share it or they are not willing to share it. The very first thing I did is to have an initiative to talk to her as I am feeling that there is something wrong as I have also experienced it during that time.

That friend of mine suddenly started crying, I can't even understand her reasons for having the struggle so basically I can't do something about it. She only keeps on telling me the emptiness she has been feeling and even her parents aren't aware of it.  I was quite happy tho because even if I can't give her solutions. she have shared it and at least let some of the pain goes away.

After that I constantly talk to her and also tell her that I've had the same struggle (tho, my reason is quite obvious it is because I can no longer live the life I wanted to because of my health issues).

To end this post, I just want to tell everyone to please have an initiative to talk to those persons who are important to you. Just let them feel that you are just here willing to listen to their problems. By doing that you might be able to save someone's life.
