So it's not always sunshine and rainbows but you're 26 and there are many people out there you likely click with that you have yet to meet + people generally growing more mature as the years go by.
It's up to you to decide whether the effort it takes to cultivate a healthy relationship is worthwhile, or whether you want to focus on other joys in life. Making a firm decision and pursuing it contains a power that merely ignoring a feeling or acting on a whim does not.
