That’s a shame. Hope it works out.

1. “My blood test results just came out” → “My blood test results just came back” • “Came back” is more natural in this context when referring to the results of a test. 2. “what the heck is going on here!” → “what the heck is going on here?” • The exclamation mark should be changed to a question mark since it’s phrased as a question. 3. “It feels like I were allergic” → “It feels as if I were allergic” • “As if” is more standard than “like” in this formal construction. 4. “given the fact that I often slept” → “considering that I often slept” • “Considering” flows better and is more concise than “given the fact that.” 5. “a few injections” → “some injections” • “Some” is a more natural choice than “a few” in this case, making the sentence sound smoother.
