It's good to be able to experience solitude without freaking out. It's good to be able to keep your own company and still maintain your happiness.

But if you ever wake up, in this state of isolation, and it feels like your chest has been hit with a sledgehammer then you're probably in the process of healing.
Hashing out old pains and coming to terms with them is necessary.
Like having a bad break up with a lover. You go into hiding for awhile. Soon, you're okay and you're happy again and it's going to be okay because now you're ready to embrace a new relationship because the old wounds have had time to heal.
Take the same situation but instead of going into hiding, you immediately go out to find another lover to heal the pain for you-what are you really doing? That would not be healthy.

I think you're taking a healthy route to take time out to take an inventory of your life and figure things out. You're not just covering it up with a lot of noise so you can pretend like it's not there. (So many people I know, do this.)

Learning to make yourself happy is a very positive step.
Don't put yourself down for it. When you're ready to get out there again, you'll know and do what you need to do.
