I know exactly how you feel Sirensong18!
I Am a few years older at 31 but I am going through the same thing ...i have moved around a lot in the past 10 years and it makes it even harder for an introvert like me to find/make friends. I have no family or friends in my current town. My family lives 3.5 hrs away and see them 2-3 times a year.
I have a lot of online friends,and that's cool and all, but i can't call them to come over,or go shopping or do anything. I am married but I don't want to burden my husband with my depression because he is dealing with anxiety and panic attacks (making my depression worse). i have no one to vent to ,no shoulder to cry on,no girlfriends that would invite me to buy ice cream or go dancing... I work from home and although is pretty awesome to work in your jammies ,it's not so awesome when that is all you do.

Thank you for your post. I joined this forum because of it!
