depression and anxiety

so the past few months have been horrible for me. People always say “I’m here for you” and “it will get better” but honestly I’m alone and things are getting worse. My therapist says the same thing over and over. My boyfriends been selfish lately and I wish he would be there for me instead of making stuff about him. I’m a selfless person, if I care about you and your in a bad mood I will do everything I can to help. and I help everyone but whenever something happens to me there’s no one. I used to have a lot of friends but now I have no one. I keep having breakdowns. And my anxiety is affecting my sleep, I ended up in the hospital and I’ve been anxious 24/7 ever since. I gave up on everything. I’m mentally tired.
