<human>: Can you succinctly summarize the text in 1-3 sentences?

To be brief, I'm a student/musician who has some problems it seems with maintaining romantic interests. I feel like I constantly put out but never receive much back. It's like I go through this cycle of having a person obtain a strong interest in me but lose it very quickly. I mean, they're interested enough to actively want to hang out and sleep with me for a time (Like a month or so), but they inevitably just seem to lose interest and back away.

My dating history isn't exactly very much. I had two serious relationships in high school and then was seeing someone last fall. In the past year I've been diagnosed with depression and I still suffer from it pretty frequently though I'm doing better at finding coping methods to help myself. I suppose I would describe myself as sometimes being a pushover but also someone who can be extremely supportive and not make others feel uncomfortable. I've also recently given up drinking/drugs.

I'm not sure if what I'm going through is just a normal experience for people my age or if I actively push people away by doing something. I don't really expect much of people and I kind of like to take things easy myself but I just feel like I'm always putting out more than I'm getting back and it inherently effects my mental health.
<bot>: I'm unsure if it's just really hard to find committed relationships at this age or if I'm just doing something wrong.
