To be perfectly honest, I do not feel that a simple invoking / banishing ritual will really balance your internal elements in any appreciable way. Of course, to each their own if you disagree and I totally respect that. But in my experience, internal elemental balance is a tough cookie to crack and requires a lot more than a few weeks of ritual. Personally, I think you are doing a great job addressing the physical level of the element (e.g. your T) with supplements, which probably helps to increase the fire element with you. That is one part of the overall puzzle.
A great system to look into is Initiation into Hermetics by Franz Bardon. As I understand it, you can still believe in your traditions (i.e. Aurum Solis, Cult of Ares) without needing to give up on them with his system. It is designed to be superimposable on any western magical system that is compatible with the 4 elements, 7 planets, and 12 zodiac signs. The main value here, in relation to your question, is that it precisely contains good instructions for elemental balancing over the long term and to do so in a way that is lasting rather than temporary. You can use the theoretical section and the first 2 steps to gain basic methods to help with the elemental balancing.
Based on what you described, it seems like you are trying to work with the energy of each element inside of yourself directly rather than working from an outside-in approach. This can be an approach to do things, but in my eyes it is also less targeted and less granular because you are working with the general elemental energies without necessarily having an idea of what proportion of yourself is dedicated to what element. For example, are you 30% air, 20% water, 40% fire, and 10% earth? While there is no way to scientifically quantify these proportions, Franz Bardon offers a good example through his soul mirror exercise, where you list out character traits of yourself and then classify them according to the elements they correspond to. In the end, you gain a high level overview of how much of each element you have inside of you, which allows you to begin using the work of balancing them.
As I mentioned before, balancing them is probably easier with an outside-in approach. All of the character traits you identify in the soul mirror are outer expressions of your inner elemental energies. By working to transmute certain "negative" character traits (e.g. aggression) to their "positive" opposites (e.g. tranquility), then you start to do the work of elemental balancing in a more targeted way. The main goal in this soul mirror work, is to take each negatively identified trait and transmute it to a positive opposite and reduce the negative trait's overall impact on your life. By doing this, you balance the elements inside of you in a way that will be less disruptive than simply invoking the opposite elements energy inside of you.
And the other issue with just simply invoking the opposite elemental energy for balance is that you don't even know if that is necessarily the correct way to balance the problematic element. For example, aggression is an expression of excessive fire energy within you, but the true opposite of aggression might not just be the water element energy contrary to what you expect. The positive aspects of air and earth energies can also be very powerful ways to counteract aggression, depending on what the aggression actually is. In your case, due to the recovering balance of hormonal levels, your aggression is biologically sourced. So the calming and flowing aspects of water are a good choice, but you can add even more into this by considering the grounded presence of earth energy in order to tether that aggression. In the soul mirror world, the trait of aggression itself could be counteracted by working to transmute it to inner grounded calm (earth) and gentleness (water). The risk of invoking water (and / or earth) energies through a ritual, in bulk, is that these energies will also touch the "negative" sides of the elemental characteristics within you. Water can also increase melancholy while earth can increase stubbornness, which can lead to more complications than balance.
If you decide to go with Franz Bardon's perspective in Initiation into Hermetics, look to his information on soul mirrors (step 1) and the suggestions that he makes for character balancing (step 2). He gives several methods in step 1-2, which directly facilitate this internal alchemy such as the following: "conscious breathing / eating", "the magic of water", and "auto-suggestion". You can read on these and do further research in the Bardon community to see the ways these methods can be effectively used together. You would not call these specific rituals either, but practices that facilitate the elemental balance you are looking for. The process takes longer, but results in a more permanent stable balance than the simple invocation of raw energies. It has worked pretty nicely for me and maybe it might do the same for you.
