I just want you to know that there are other people going through this. I lost my mom in 99 when I was 22. I have no siblings and my dad is not a part of my life either. I feel so unbelievably lonely at times, my mom was truly all that I had in life. Like you, my mom passed suddenly and I had no time to prepare for this huge loss. I can't say that it gets easier, it just gets different. You become stronger.
