Venting, I feel like im getting big 😫

I used to go to the gym before I got pregnant, about consistently i definitely had muscle tone. I’m 13 almost 14 weeks now I flexed my arms to check and it’s barely there! Omg the body changes is really hitting me. My big belly and now my arms just look like arms. My baby doesn’t even have a dad, my freedom is gone and so is dating life I’ll be in my 30s when my baby starts school idek if all of this is worth it anymore how strong do I need to be

Edit: I had a stressful and sick first trimester so i stopped working out. I’m interested in going back now that the nausea is gone but I’m still tired
