I need help!

I'm 5'6" and 160 and gaining fast. I had a mc back in may and since then I've gained almost 20lbs! 😢 My clothes don't fit and I have no energy and worst of all I think it is affecting our TTC... My husband tells me constantly I'm not fat but looking it and feeling it are 2 different things.

I want to make a change for the better! I have terrible self control around food so I think that I need to start there....what can I do???
