TL;DR Summary
What is going on in electric attraction Feynman diagrams?
In Feynman diagrams, I believe two like-charged particles will "blast" one another with a photon, thus pushing each other away because of the law of conservation of momentum. How would this work for electric attraction?

A Feynman diagram is not a picture of what gets "blasted". It is shorthand for a term in a mathematical calculation.

It's a bit "risky" to ask for verbal explanations about subatomic phenomena and/or their mathematical description. As Vanadium 50 said, Feynman diagrams fall into that category.

However, if you only worry about how to describe both attractive and repulsive events in QED, you can find a nice passage in Zee's "QFT in a Nutshell, 2nd ed.", section I.5; it's on the math side, but the text between the equations is readable.

Thread 'Toponium Discovered'

Toponium is a hadron which is the bound state of a valance top quark and a valance antitop quark. Oversimplified presentations often state that top quarks don't form hadrons, because they decay to bottom quarks extremely rapidly after they are created, leaving no time to form a hadron. And, the vast majority of the time, this is true. But, the lifetime of a top quark is only an average lifetime. Sometimes it decays faster and sometimes it decays slower. In the highly improbable case that...

Thread 'Dirac-Delta from Normalization of Continuous Eigenfunctions'

I'm following this paper by Kitaev on SL(2,R) representations and I'm having a problem in the normalization of the continuous eigenfunctions (eqs. (67)-(70)), which satisfy \langle f_s | f_{s'} \rangle = \int_{0}^{1} \frac{2}{(1-u)^2} f_s(u)^* f_{s'}(u) \, du. \tag{67} The singular contribution of the integral arises at the endpoint u=1 of the integral, and in the limit u \to 1, the function f_s(u) takes on the form f_s(u) \approx a_s (1-u)^{1/2 + i s} + a_s^* (1-u)^{1/2 - i s}. \tag{70}...
