How to deal with relationship anxiety?

I overanalyze everything.

I hate it.

I’m really happy with my boyfriend and I’m scared of losing him.

I want to be good enough.

As soon as I notice he texts “different”

I assume the worst that he doesn’t want me anymore and that causes me to ask him a million questions.

We were on the phone the other day & I was like “is everything okay?” And he replied with “we just don’t have much conversation.”

LIKE WHAT IS THAT SUPPOSED TO MEAN. I want to work on it. But it makes me feel bad. Now I just wanna break up. But deep down I don’t want to run away from something so minor. I’m so confused.
