My son cut contact

After a psychotic episode I was hospitalized I felt ignored by my adult children I lived with. After 3 weeks in hospital with 1 visit I asked them to move out. Once home I had an empty nest. I was a single parent for 20 years and regretted my harsh decision. 3 months later after seeing a psychiatrist I was diagnosed with Bipolar 1 disorder at 51 years old. I have emailed my son apologied but he has made no contact in 6 months. My daughter and I have talked about it and she understands I was very unwell and can see the work I've done to get better. I've spoken to psychologist and she said I need to give him space. No contact is breaking my heart does it get better.
