Hey there,
As I was reading your post I noticed how attached you are to other people. Don't get me wrong, friends are great, but they should never be a priority in life. Sometimes your life changes and you need to be in a different place, behave in a certain way and want different things. Whenever you do something major in your life you will lose buddies. That's how it is, most people won't be able to keep up with you and there is nothing you can do about it.
Also, you seem to believe that loneliness is bad. Silence is a bliss. Become friends with it. Breath it, feel it, immerse yourself in it because you will find most of your life lessons in there. People, things, activities are distractions from our souls. We need things, distractions and other people but as men we need that silence first and foremost. Life has no real meaning if you can't live your life without other people.
It may sound strange but you feel alone because you aren't connect with your spirit and your purpose in life. You can't really tell where you life is going because if you did, you would be too busy doing that thing and less concerned about why people are not contacting you anymore. Great men who lived on this earth rarely needed companionship and approval. They loved other people's companionship but they didn't need it. And not because they were loners but because they knew deep down that at the bottom of things other people are distractions to their own purpose in life.
The Universe, God or however you want to call it brought you to this moment for a reason. There is a deep reason to your loneliness. When alone meditate on this one. Think it through and find your true friend - your spirit.
