The biggest initial issue with a nuclear war would be the repeated EMPs taking out the grid and destroying all electronic devices. The lack of communication would cause a lot of panic and stress, with daily stories of foreign invaders and threats of new bombings spreading among the survivors. Plus a lot of people under 50 would be driven crazy from the sudden lack of constant dopamine hits from social media and pron access.
The answer to your question is really whether or not you can stomach living without internet and modern entertainment for potentially the next several decades.
It would take months to years, depending where you live, before the grid could be brought back online and power would probably be very intermittent for years. However, it's not actually that hard to generate electricity, and even with EMPs, a lot of simple electric motors and practically all vehicle alternators would be fine, so you could set up your own power generation easily enough. Probably with wind power or simple water wheel designs. Once you have power, even intermittent, you could pump water from wells, maintain refrigeration and air conditioning, and other modern conveniences that would bring you back to a near current lifestyle pretty quickly. It's not really possible to knock civilization back to the literal stone age; even an all out nuclear war would just put people back to the mid-1800's in terms of technology.
If you live 50+ miles from a major population center, you'll probably survive the actual bombings and radiation. Realistically speaking, any real war would likely only target very specific cities and military facilities, mostly coastal areas. If you're well away from the coasts and any major city, you should be relatively fine in the initial bombings.
But the first few weeks would be terrifying from lack of information, and the first year after the bombings would be full of diseases spreading through an increasingly malnourished population. However, this first year die-off should take out just about everyone without a food supply. Year two would be a major improvement, as the survivors would all be people with some capacity to grow or hunt food, or otherwise have access to stable food supplies, perhaps from government programs. If you don't have some supply of food to get you through this period, you will not survive this first year.
Things would be moving back to semi-normal status in the less isolated areas by about the end of the second year as the government remnants solidify their political control and begin rebuilding basic infrastructure for communication and power production in surviving cities and larger towns. That period of rebuilding could last between five years and several decades, depending on how far you are from those towns. After a decade things would be largely back to normal for most of the population, at least in first world nations. No idea how long it would take to get back to current computer technology being widely available, probably decades, but some sort of basic phones and older-style pre-internet computers would be buildable in country fairly early on. We'd be at 1970's tech for probably twenty plus years, but once microprocessors can be built again, things would jump forward rapidly.
