I’ve had a mentally trying day and just am filled with anxiety now. Would love to hear or see some happiness

I had a best friend of 20 years but that went down the drain a couple months ago. I miss having a best friend to talk to especially when it’s been a hard day. My SO is obviously my other half, best friend and nobody could ever replace him but there’s just nothing like having a woman best friend outside of that idk. Idk how to explain it. Ugh
