Post partum weightgain

I gave birth 14 months ago, and since then i have been putting on weight so much that this is the heaviest i have been in my entire life. During pregnancy i did not gai much weight but now i look very unkept. I do breastfeed as well

I have a very clingy baby with husband working full time

I need some basic guidance or a course i can sign up for from home. Need help 😑
