So, i need help, i know it's ridiculous that I'm here asking random people rather than going to a professional

I'm in a relationship 2years na, we we're cool, we're both open minded and mature enough I'd say

the thing is, im afraid, im questioning my self and my love, what if it was not love after all? what if it was because I was longing for affection? what if kaya lang ako kumakapit sa relationship na ito it's because matagal na and sayang ang oras

there's no third party involve, im not having any feelings or affection to anybody else, it's just me.. can some share your opinion, im having panic attacks hehe​
