carer needing advice

Hi,
Am a volunteer carer for a woman for the past 16 years and also a carer for another woman for the past 9 years which is still ongoing for both and has been a very hard road to navigate all these years but have seemed to manage until the last few months hence me finding this forum to ask for advice as I can't seem to get the carouge to see a phycologist so what has been happening I get the sudden urge to cry for no apparent reason but what seems to trigger it off is a song on the radio or just a thought or memory from my past and the crying episode can last for up to 20min or longer . any advice would be greatly appreciated.
