I will venture out and say things differently. You are being moved forward faster than you think. People in your influence are being fazed out of your life that will not serve you. Let it happen as new ones will come in and will be in better in sync with your energies. Do not hang on to that as it will hold you back and prolong the obvious. It sounds weird, I know but test this out.
Empaths often feel on depths that most people don't care to go in their own lives muchless in someone else's. I can't tell you how many times I would have friends or even strangers dump all their problems on me and then feel better, but when I have a problem or need to talk, they don't want to hear it. They will blow it off like it's no big deal or they don't contact me for a time. I don't have alot of friends as it is. I've learned to accept this and I have learned that there are very few people who will ever understand that depth of emotion. It's uncomfortable to them. This isn't just the negative feelings either, sometimes it's also the positive ones. But there is a reason for this ability and there is a reason why you have it. With the gift also comes acceptance, accepting part requires you to accept it all.
You have an outlet here, people who do understand. So maybe the answer isn't being alone, maybe it's understanding your gift and how to deal with others who don't fully understand it. When we make connections, we make them quickly so if we have a best friend, we could have met them 2 weeks ago and feel that we have know them our entire lives. But in their time, it's only been to weeks. So truely letting go of our emotions will scare them because they can be so deep and powerful. For some friends, it may years if ever, because again, they don't even feel that deep themselves. We want them to understand, but often we have to accept that may never understand. It's hard to hide that side and it feels unfair to not be able to fully express ourselves to the rest of the world, but we also have to understand how they perceive us as well. And that is why an outlet is so important. I usually don't post deep things on facebook. To much drama from family and friends going "what??" So my outlet is usually coming here and writing a blog. Just getting it out and not once have I ever had anyone tell me I was nuts or anything. Decide with your friends what kind of friend they will be. Is it a friend to hang out with on the weekend to have a good time? Is it a friend you can talk to about your abilities or other things in that nature? You may have to split friends up in a sense, like, these are your buddy's to go play pool with and on Thursday's, these are the people you hang out with during meditation class or some other type of meet up.
I have been with my husband for 8 years now, and though he has a greater understanding of my abilites, he will still never fully understand. He see's the extremes of both good and bad emotions and we have had to compromise on alot of things. I've had to tone it down or find other outlets just to let it out. but he has also seen the benefits of it. he see's the loving and caring side of it and it has also allowed him to open up more as well. Most of the people who come into your life will be there for a short time and for a reason, a purpose, often healing or something for an Empath and then they will leave. Once in awhile you will find a soulmate. These soulmates are the one's who it will be easier to express your true self to because they already know you, but they are human do, and still won't fully understand. Maybe take some time to learn about different soul connections, this may help clarify who these people are in your life and what their purpose is. This may also help you understand what it is your truely looking for. I hope this helps.
