depression and anger over being used by brother that took all my money did not repay any

MY brother a few yrs ago got in trouble because he didnt contribute to retirement
plan where he worked but he paid the employees retirement. this was illegal
he was looking at divorce losing his house and job and his standing as an
elected official--possible jail time. i handed him all my retirement money ===
i only had 45k recently rolled into my retirement fund. i had to pay irs a lot because
i wasnt retirement age when i got disabled. he said he would give me his land
he would inherit when our parents were no longer with us. he has not ever even
mentioned or paid any thing back to me. nor give me his land. i cannot sleep
have anxiety and hatred for him. can anyone help me get over this? i cannot afford therapy. i am 70 now and i do without proper food and live off ss check.
my brother lives high-buys exp guns gifts for his friends takes them to eat never
asks me. this squandering by him has turned me against him. he does nothing
for me. someone please give me advice about letting this gol i have a lot of anger and resentment to him. he will never pay me anything back. thanks .liz
