Dropping out of high school

For the past year my anxiety and inability of properly function around other people has gotten so severe that I'm contemplating dropping out of high school for 11th grade and completely taking a year off to work and rebuild myself untill I'm able to be around other people again. To my suprise my dad who is very supportive told me he doesn't give a shit if I drop out as long as I continue to fight my problems. The rational part of me is saying that this decision would fuck my life up completely and isolating myself would only handicap me further but the anxiety has gotten so bad that I might just have to do it. Please help me with this
