Depressed

I’ve been super depressed for no reason. I’m 18 single mom n I have my friends n family but I just feel so alone.. It’s like I’m happy but then get sad randomly for no reason.. so bad that sometimes I wanna end things.. I don’t tho bc of my daughter n family.. my friend killed himself a month ago n my uncle died last week of drugs.. life sucks n I’ve been going to the wrong path too but I’m trying to be better... I don’t do drugs or anything I just go out too much n party n smoke weed or drink beer n go w a lot of guys.. I know I’m wrong but when I do that I feel happy but after I’m back to normal. I hate feeling like this I don’t choose to.. I believe in God n I have hope that things will get better.. that’s the only thing that has kept me going is hope n my family... no one really understands how I feel tho. 😣😣😣😣😣
