Lonely 😞 and depressed

My ex slow fade on me before a month for no reason ( he used me just for sex)

I feel lonely... no one to talk to... my sister is selfish she won’t listen to me..

I got some friends but am not comfortable in sharing my personal experience with them. We are not very close..

I don’t how to express my feelings after the breakup... somedays am fine but some days I feel my heart is broken... am missing him... also the feeling of blaming myself that I let him use me...

I feel weak, I can’t move out of bed.. it’s been a month but I just can’t move on easily..

I don’t know wt to do...
