Yes! Support is also the part most potentially terrifying to me, considering starting something while still employed at a full time job. Seems like it could quickly become a massive time sink and source of stress.
I love doing support actually. I love talking to users, understand how they use my app. I have 600 Slack threads open with them. Any confusion, bug fix, etc... is an occasion to improve the app and learn from them.
it's actually a really great way to understand your customer's needs, and your products actual (in the eyes of the user) deficiencies. I also use uservoice to help the highly-desired features/requests to "bubble up" but if a customer asks for something and it's an easy enhancement I go ahead and implement it. Likewise if the same problem is annoying a bunch of people, I need to either document a workaround or make it easier.
