lacking in patience

Hello! I had surgery 3/16/2018 and while the early recovery was rough, I've felt much better until recently. I have a nagging pain on my left side that is sharp when I breathe in deeply. Doctor had me cut back on workouts (that is where it started) and intensity and cut out raw veggies, but it's not getting better and not doing what I think I'm supposed to be doing (those damned "shoulds") makes me feel like I'm going to gain weight. My weight loss has been slow, in 3 week plateaus before it drops for a couple days and then plateaus again. In my pre-surgery life I was always trying to out exercise my bad diet, and even though my diet is so much better now, I still feel like nothing will happen if I don't workout intensely. I think my body just needs more time to adjust and heal, but my head wants it to be ready NOW.

Anyone else with weird pains several months later?
