I am so sorry to hear about your loss of poor Lelouch....... it really hurts when we lose a finned friend and although you may feel strongly about not getting another betta now in time when your wounds start to heal you may find yourself considering bringing another betta into your life......
When I lost my first ever betta George I did not think I would get another one but a month later I came home with Leo my new red boy...... I have had about 30 bettas since then, it was hard losing George but I am so glad that I did not give up on bettas.........life is definitely better with them..... they always brighten my day
