I feel like my husband will leave one day

He puts up with all of my bs. And I feel like one day some easy going girl is going to come along and he's going to realize I'm just not worth it anymore. I'm too difficult, moody, messed up.

I'm trying to change. I went to a therapist this morning for the first time.. she prescribed me antidepressants on the spot and I started them and I hope they work.. or one day I feel like he's going to get tired of me I feel like it's inevitable.

A girl he works with had invited him over for drinks via text and his response was he'd love to be able to get out of the house. The texts were about work and she mentioned having people over for drinks and that was his response. He didn't tell me, invite me, mention it at all. I just saw the texts.

I just don't know what to do. I am trying. But it's not enough.
