Wetsuit to small-to big

Hello, here is my question. I am 6'3, when I stared doing tri's this year I was 248lbs with large chest and shoulders..Ok and belly..Anyways, I bought a 2XU XXL full suit and it was so tight it was hard to breath when I would swim, so I had it altered and it fit great..However, now I am 214 lbs and plan on loosing another 6 to 8 lbs and as you may have guessed the suit is now pretty loose. I have my last race in October (HIM, first one, I am so stoked) So here is my question, should I sell it to someone that was in the same position I was and get a different suit or just use the one I have? Thoughts?

As a side note, this is my first time posting anything and I just wanted to thank everybody for there past comments/answers you all have helped with a lot questions, thanks...
