theres betterhelp.com (they offer discounts) and there's talkspace -they both do chat only therapy, with one free 20 minute session a month. you can pay for extra phone time but theres no allowance for video messaging.

i have found it to be just okay. they assign you a therapist, you dont get to pick- they pick you, or you wait forever to be picked by someone. I didnt like one of the people i was matched to, she was a cold fish. but it was easy to switch to a new one, i just had to wait two days for someone else to choose me.
