I think it is quite common for people in this section to feel that way.

What is hard to know is what is just a normal part of your nature and what is a problem for you.

For example. I have always been shy and introverted and had what is called a "flat affect". Meaning I never smile much or show much outward emotion even when I am feeling it inside. I never liked this much as people would make comments about it. Once I get to know people and they get to know me I form good friendships but it takes more time. It's a normal part of my personality that hasn't caused me a ton of problems.

On the other hand a couple of years ago I was in such a horrible depression that I didn't even look at my phone or touch my computer for four straight months. I was in total isolation as a result of the depression. That is a problem.

Sounds like some things are a part of your nature and you would like to change as they are causing you problems. I don't really know how to change what is innately part of my nature other than to accept it. I can make changes in my behavior though. Like if a friend and I run into a group of his friends that I don't know I tend to stand back and not say anything. So I try to force myself to be a little more outgoing and step up and introduce myself and do the small talk thing. I feel better about myself and more connected when I do that. Forcing myself out of my comfort zone makes a difference.
