First of all,
for what you've been through.
I don't know if your goal size is lofty or not and I wouldn't be able to tell you since our bodies are so different and we lose in different areas from them, stomach, legs, arms, hips, boobs, etc. I'd just make the best of it from now and until then.
Perhaps you should come and join us at this Bikini Ready Challenge
, it goes on until July which I think may be perfect for you and you'd have accountability & support as well! You CAN do this!!!!
