Hey, Don't be so hard on yourself. I mean we've all made mistakes but the best thing is to learn from them and not repeat those mistakes.
First off, Try not to do the rejuvi removal one right after the other. I mean spread them 2-3 months apart so that your skin can heal itself and that also gives you time to save up some money.
Please don't get the machine gun yourself, let a proffesional handle it. 2nd, if you believe in God, Pray to him and ask for forgiveness because we have offended him. We're suppose to be treating our bodies as temples. Don't get a cover up, As you said, you would still know it is there and it would just be making things worse.
Yes I know what you mean about turning obsessive with them because I find myself constantly searching for ways to undo them also n' of course I wish God would have pulled me away from that tattoo parlor because I was so young but as I mentioned in the last post, I've forgiven the people who gave me the tattoo n' sort of myself. Life is toooooo short, Please live it, don't let it live you. Forgive yourself and your ex....that's a start. Then take it one step at a time.
Also, emu oil is what I use on n-e fresh wound and it helps lessen the scars that's if you put it on before it heals. This oil is amazing and so is God. Try it, right after your rejuvi sessions. Put a few drops on the site 3 times a day until you feel no pain in the site. It also reduces the pain within a few days.
Good luck and keep in touch and I will do the same.
