I'm not going to hang out with my friends
Why don't you want to hang out with them?
I don't know where to go, this was a long month
Your friends will understand if you need some time away, if they are your true friends. Take the time to figure things out and where to go and then come back to them later.
This was hard month since I had to spend some time working alone. Hanging out with friends is hard and I had a lot on my hands.
If you find it difficult then definetly take a break from friends, and then regroup later. Being so busy can be overwhelming, you need to rest first.
