Well done - that's actually a good start!

Coming out is often the most difficult thing, and you'll have to keep doing it, again and again. The way your Dad reacted isn't uncommon, unfortunately - but you needed to get over this hurdle before you can get anywhere else. Try not to take what he said to heart: you know he's wrong about you being a 'freak' and he was reacting out of shock & anger; in time he'll get over his initial reaction and he'll eventually come round, but it is going to take time. For now, try to pluck up the courage to not go back into the closet again, but to keep gently pushing forward.
Please take a look at the responses to your other thread, if you haven't already done so; there are some helpful tips for how you can manage this going forward. If you're continuing a conversation on a particular subject, it's helpful for you to keep it to the same thread rather than start a new one.

In particular, if your Dad said you need help, search
here for a Gender Therapist near you and give your Dad their contact details - tell him you do want help with this and ask him to book you in with one of those therapists. NB: not a 'reparative/conversion therapy' therapist who tries to talk LGBT people out of our identities. Those are a waste of time & money at best, and actually harmful at worst.
