SB – I’ll be honest, while it is very admirable to want to do chesed, your first priority should be to learn as much as possible now before you begin to look into getting married. This is the time to focus as much as possible on growing and deciding what your derech in life is going to be – MO or Chareidi or somewhere in between. You will not have the opportunity to engage in full-time learning after that. I see the difference between myself and my siblings, who are also BT – I came back before I got married and came to EY and learned for 2 years before I looked into shidduchim. They were fortunate in that their husbands and children also came back together, but they never had more time than the shiurim given in their neighborhoods, which is great but all of their growth had to be basically self-impelled.
Chesed is a lifelong obligation and you will be doing tremendous amounts of that after marriage, with husband and future children, iy”H. I don’t think you need focus on that as your growth point right now at your age. Think now about yourself first (chesed starts at home).
