Hi there,
It seems that what you really want is a connection to them, and unfortunately they're not feeling that towards you. They might have one, but at least not on the level you want, and you can't force that. It seems you're looking for your friends to fill a certain void in you, a closeness, where you feel the other person really needs you around. A friend can't fill that void for you, nor can anybody. When you approach situations in this way it will come from a needy place, more than a secure one. Even though it really sucks, you will feel better if you can learn to feel good on your own, and not think you are dependent on others to get your emotional needs met. I know first hand to really like someone and want that connection (and how horrible it feels when it goes away). But you really should be thinking, why aren't they upset about issue as much as I am? If they're not thinking about it, why am I wasting so much time and energy on them? They should be worried about a connection with you, not the other way around. If they're not, then they're not worth the extra thoughts you give to them. I know you might feel they are special, but what makes them so special if they're not reciprocating the warm feelings and gestures you've been giving to them? You need to know you're deserving of a true connection, and if you're not getting it it's a lesson to move on, because there are people out there who will give it to you, and think you are deserving, and it will come from an organic place because you both will feel it. You should try to focus your attention off a situation you have no control over, and look for the better ones. You will find them, and will feel a lot better about yourself, instead of feeling less worthy because someone your focusing on doesn't seem to think you're as wonderful as you really are.

Keep being the generous kind hearted person you are,
and focus on the good connections you do have. You will attract
those who are as caring of a person as you are.

All the best to you
