Don't want to talk to friends

I haven't messaged any of my friends back for months. I haven't also seen any of them in months. I don't want them to talk to me, I have a support system at home and feel like it's difficult for my friends to see me anyway as I live in another town now and I'm a parent.

When they message me it puts dread in me, like the idea of responding abd rhe burden of replying to a conversation. Then it just goes on too long and too much time passes so I just ignore the messages. They are all messaging me saying they are worried about me and even messaged my partner to ask if I'm OK as I have cptsd, ocd and anxiety/depression.

I feel my mental health is stable (ish) atm I'm just burnt out from parenting and stuff. I just feel like I dont want friends and its too much effort then I get emotional to my partner BECAUSE I have no friends. I know if should just reply bur my brain is telling me no and keep everyone away from me.
