<human>: Could you distill the essence of the text into 1-3 sentences?

I broke up with my boyfriend of 7 years in the spring. He's a good guy and nothing bad happened between us - it's just over the years the love/romance disappeared and I began to resent him. I wanted to be with others. I don't think he was someone I want to spend my life with, for many reasons. I still feel this way, I don't want to marry him (which was our logical next step).

Now that I'm going on 4 and half months of being single, I find myself depressed at the thought - "what if i never find anyone?" This is something i've never had to deal with as I started dating my ex when i was 16. I panic sometimes. I used to wonder why people used to roll their eyes at romantic pictures and such, and now i see why - sometimes my stomach sinks and i legitimately get depressed. I know I'm young and recently single and such, but it's really starting to wear on me and I want to know if others feel this way, and if so, how do you deal with it? I don't have single friends, i don't even know where i'd meet someone. I worry that the fear will hinder my interactions if/when i do meet someone else.
<bot>: I'm just sad, lonely, and scared for the future because I'm single. I know i can't go back to my ex because of it, its not fair to him. help :(
