Just need advice

So I’ve dealt with anxiety my whole life never been to a doctor or anything just haven’t gotten around to it. It’s gotten worse this year. Got engaged in June. July I had my first miscarriage with my first child with my soon to be ex fiancé. November my fiancé leaves me because I am “too much” and I literally didn’t even see it coming. He gets to keep the house we bought a year ago but we’ve decided to sell it and he still wants me to pay half the mortgage while he lives there. I still have 2,000 worth of hospital bills because of the miscarriage and he won’t help me. I’m floppin back and fourth I’m being okay and I’m not sure what to do. Ex fiancé has already found someone within a week of him leaving me and I had to move back in with my parents (I’m 21 he’s 23). I just need advice. I go to work some days perfectly fine and others I’m just breaking down. Same for going home. Or during the day randomly.

Thanks for any advice
