Self conscious| body issues

I'm very self conscious about my body because ever since I stopped doing sports I have gained alot of weight in my inner thighs and stomach. I even have stretch marks on my legs and I feel embarrassed to wear a bikini or shorts sometimes. I like doing blogilates but I just can't stay motivated to do it every other day.

I also have acne on my face, chest and upper back. I'm very self conscious and I have tired everything to get rid of it on my face. I have been struggling with acne for 4 years and now I just get so frustrated. Plz help
