Get patches etc and support on the NHS if you want to and then try and reverse the same path you took into using to get out of it. Stay focussed on the better day today, and reward yourself for tomorrow.
You will have started off at no nicotine intake or no vaping - Why did it start, how did it start and how did it increase to the point you are at today? What does nicotine do for you in your day to day living? It is your relationship with a drug and your life that matters. Why did nicotine become so important for you? Best advice is either go cold turkey or drop one small input a day for a week, then drop another for the next week so you change one small thing a day. If you vape create a strong imagine of your lung alveoli filling with pus and slowly suffocating you to breathe. There are a lot of serious complications and lung injuries associated with vaping - why suck in so much cr*p into your body when you don't have to?
If you use nicotine as a pattern habit work out what your triggers are. Be ready with displacement activities to get you away from the stuff as soon as a craving hits.
No one can do this for you - it is your choice and your decision to quit
