idk what to do anymore

I would never do anything to harm myself for starters. But i just don't know what to do anymore. I've had anxiety and depression for a long time now. I'm on an antidepressant and since it's getting worse again I've scheduled an appt with my therapist but it's not for a few weeks due to how booked she is. I've been having a hard time due to health problems but then this guy came in my life who I never thought I would be with but I finally fell for him like I thought he was the one and out of no where he went MIA on me. Ignoring me and everything. I'm so hurt and heartbroken and I wasn't in a good spot before and this just pushed me to the edge. I can't stop crying I just would like advice of stories of how others have got thru a break up or the hardest times of their lives
