Don't you hate that feeling when you get lonliness and it feels like it's going to make you vomit? 
Yes I do hate being all alone. That's how I feel when my boyfriend leaves town for work.
:( Long distance is hard too! I just have to remember for myself that it is better to be at peace then to deal with horrible drama.
Yes you have to do what is best for yourself. Take care of you before others.
