Why Now?

I have been married to the same man for 10 years. We were together 3 years before marriage and had 2 kids together. Our marriage hasn't always been good. It's been hard, but he's the man I love and want to be with. Forever.

But lately, my anxiety has me thinking things are bad. Very bad. I know a lot of it is because of losing our newborn in April, then miscarrying twins in October, but now I feel like I'm losing everything else.

He's never given me a reason to believe he's ever cheated or ever will, even in our worst times. He's never given me a reason to belive he's going to leave me. But for some reason, I feel like he will. I feel like it's only a matter if time before he gets tired if me not being good enough and moves on.

It's putting strain on our marriage again. I know it's me. I'm in therapy to work through issues, but please give me tips to deal with this now!?
