why would you be negative about something good in your life?

[Jenna Dak]

I was unsure about my bf after 2 months i guess i was scared it wasn't gonna last now is been over 6 months and i was so happy but the feelings came back....idk if maybe because i was worried about something else during that time. I know he's very good...is like i have to be worried about something to be "normal" what should i do? my self esteem issues came back too
