I was so tempted to post a picture of Charles Atlas here...
Be careful...your age is showing if you know who the 95 pound weakling was...
Actually, I was looking for a new body myself. Lose 50 pounds, regrow a head of hair, build some muscles so I could be a body-double for Arnold Schwartznegger in his body-builder days...
But for camera bodies, there's a number of options, all with various costs and 'added features'. Without knowing what your budget, what is lacking/limiting with your T3i, or even what you usually photograph, it's difficult here in the cyberworld to give any meaningful suggestions.
It's also possible you are catching the dreaded GAS disease...
Gear

Syndrome. Many photographers get this disease at an early stage, experience-wise. At least it's not fatal...except to your credit cards...as in 'been there, done that'.
Actually, with 3 lenses and a decent camera body, perhaps the best path to take is to figure out what you want to photograph mostly, figure out what is needed to do that, then buy/replace/sell as needed to reach that capability. It would not make sense to buy a macro lens and find you don't have any interest in photographing creatures smaller than an inch or so....or jewelery. In essence, just buying for the sake of buying not only gets expensive, but can result in having to replace the new stuff once again once your needs/goals are become more 'known'.
As mentioned above, perhaps a flash unit might be a good next step, especially if a good portion of your photography is indoors and the pictures you are taking are noisy due to too high an ISO speed or blurred because of a too slow shutter speed. My goal was/is to do low light photography without a flash. I figured out what I needed and started buying what I needed. In my estimation, the three most EXPENSIVE niches in photography are sports, wildlife (incl birding), and low-light (including weddings).
Hopefully, you have or soon will figure out what kind of photography most interests you. THEN get what you need. An oft repeated saying I have heard many times: "if you don't know where you're going, you won't know when you get there!"
