Feeling lonely whilst pregnant

I know its normal to feel lonely when pregnant but did anyone feel lonely before pregnancy? Ive had alot go on wherw i cared for my grandparents and even more one one of them died i cared for the other alot more. I felt i lost alot of my social life and my friends, i had covid after my last grandparent died and still have long covid now! I didnt really have much support all through this time even my family who were more focused on themselves. I went from having a busy social life going abroad 3xs a year to just working and caring for my grandparents till they died. When they passed i really didnt know what to do with myself and had one friend left. I used to have a good friend online who then found real life friends so we dont talk all that much now either. Since being pregnant i thought people may of reached out to me but no one really has bothered. I had one friend who did but all she wanted was for me to buy he old child belongings! She didnt even ask as much when i was due or what i was having. Im due in 3 weeks and feel really lonely! Im on maternity leave now from last week and worried about my mental health. My hubby works nights so i will be alone most of the day and no one really comes around to see me at home prior to me being pregnant. I speak to my mum daily but all she ever goes on about is im so serious and i never laugh. She trys to make jokes but i personally dont find her funny what she says. Im capable of laughing i know that but she gets a cob on when i dont laugh at her 😂 sorry for the vent i just needed too off load bcos how i feel.
