We get back reflections of ourselves. If we are interested in something, we are interested in it and it looks rosy. If we hate something, we hate it and don't have anything to do with it. If we are unsure of something, worried about something, that anxiety and unsureness comes back.

The best habit/trait I have tried to cultivate in myself is curiosity. Being genuinely curious about others gets us to forget ourselves and the other person is flattered and gives us some of themselves. Being curious about a subject, we learn. When I am anxious, depending on time of day (hate night time :-) I choose to ignore, investigate how I can "fix" or get curious about what is going on with myself. Ignoring only works for a little while before it comes back. If I can ignore well, I might get to sleep and the morning sun will keep it away until the next night :-) Some anxieties, like money fears, I can think of ways to learn more and work/get more experience so I don't have to be afraid, the problem is not unknown anymore but a known project I can work on. At night I can think of one or two actions I can take about a fear that will put me on the road to not needing that fear anymore.

Curiosity is longer term and more subtle, I have a history of anxiety and worries about being able to care for myself and my husband's and my ages are getting up there (my husband is 71 this year) and eventually he is going to die and I'll be both without him, the love of my life, and on my own and old, etc. Nowadays I read books written by widows, novels about losing lovers, texts on gerontology. The biggest difficulty I have is putting everything "together" and keeping a firm hand on my imagination (the root of all my worry/anxiety).

I have taken/take courses online and join online groups (like this one) and practice interacting with others and that spills over into my actual life so I treat it like I do my online interactions :-) This about it, you made this post, you are reading these replies, etc. Keep that up and keep living/trying things and slowly some things will get easier for you because of experience.
