I'm new and just recently out so take that into consideration in considering my answer, but something that really helped me solidify my feelings and help me know that I'm sure was talking to others person for the first time. I don't know your situation, of course, but the first time I actually got my feelings out to other people was very helpful in affirming who I am. I don't find myself having worries about regrets or second thoughts, but again, I'm just out and maybe those feelings might come to me later?
