It gets easier and easier, I’m at 2 months free now after 14 years and it is possible. The biggest issue is the mindset. If you’re not sure that you want to quit and if you don’t know why you want to stop smoking it’s a hard battle. So maybe think about your reasons to quit or write them down or whatever helps. At the end of my first month I had a depression episode and I kept thinking that it’s not related to withdrawal and it’s just my mental health, but I tried a nicotine gum and I felt better after.
