This isn't for relationship counselling (in fact I struggle with relationships as they terrify me!), but esteem issues with a bit of life coaching. I also have social anxiety.
I looked up Relate, but the reviews averaged 3 out of 5. I only work part time, so I can't pay out too much. I tried talk therapy through the NHS, but the counsellor was too immature and sniggered when I told her my problems. I looked up the bacp therapist directory, but there are hundreds 😱.
TIA.
