Healthy weight

So I was always 130-135lbs literally from high school through college, my weight always fluctuated 5lbs or so. I also was an athlete from 3-18 so I was working out 2x a day and on simi strict diets for competitions.

I am now 25 5’3 and I’m at 145lb-149lbs, I have recently discovered I have hypothyroidism (a disease where my thyroid gland doesn’t produce enough hormones) there fore I am medicated now which makes it harder to lose weight (or so I have been told).

I am getting married in 8 months, I don’t feel I look how I want to, my condition make it hard for me to really feel productive and active how I used to be because I am always tired.

Just wondering what others my height/age weigh, I feel like I’m over weight but I also never had a period in my life where I wasn’t working out every day (which I rarely see a gym now).

I don’t “feel” fat, I fit into smalls and 2-4 jeans but I just don’t see myself as looking great...

I don’t know if it’s the wedding stress of feeling like I have to look amazing for one day or what but I need someone to help my mind from wondering ☹️
