Weight Loss ! I am so motivated to keep on the same track!

I struggled with weight all my life.

My highest weight I have ever been was 315lbs

I then went down to 307lbs

And I just recently found out I'm 302lbs now I'm almost back into my 200's. My goal weight is 150lbs

Not only am I doing this for my self but for my future of possibly being able to have a baby. I want a healthy pregnancy ( not saying when your big you can have a healthy pregnancy ) what I'm saying is for me this is unhealthy because im considered obese class 111.
