Finding help: where sholud I go?

Hey everyone, just hoping someone out there can point me in the right direction. I'm in Kent and feeling pretty lost when it comes to finding support. Heading to my GP isn't really appealing, and all my family is a good 3-5 hours away. It's tough being an empty nester too-my kids are grown up now, one at uni and the other working far from home. We've had our ups and downs since their dad passed a few years back, but they're doing well despite everything. Still, there are times when it all feels overwhelming. Any recommendations for support groups or something similar in south Kent?
