Hey War182,
As other captains have said the Cleveland has many good things going for it just not a heal. Some specific ships at tier VIII have a heal but it is not a common consumable at the tier. There are some things you can do while you play the Cleveland that can help mitigate not having a heal. First off you have to play the Cleveland correctly, you have a lot of utility if you learn to use it correctly. The Cleveland is not a ship you should be brawling with, it is a light cruiser that is best suited for the support role. You can get into the fray once then enemy team is worn down a bit, but if you are the first one in and the focus you will sunk quickly.
Tips for the Cleveland:
Take advantage of her high arcs and use islands as "armor". This is a tactic that can be used by most USN cruisers regardless of tier/type.
Be a good teammate and what I mean by that is use your radar and AA to help teammates that are close.
Don't be the focus of the enemy team or you will get destroyed quickly.
What makes you think the Cleveland should have a heal? Honestly if you don't find the ship fun to play, find a ship that you do find fun to play =).
