Needed to vent

I feel so stupid I been dealing with depression for a good while now and it’s been ruining all of my relationships especially with my boyfriend he’s amazing and I just can’t keep putting him through bs with all my sadness he has a lot going on with school and family and friends I don’t feel like I’m important we broke up because I feel that eventually my depression will ruin our relationship like it has before my best friend is the only one I can talk to but she is busy to with her son and boyfriend so I try not to bother her I just feel alone and going back to my boyfriend will just ruin him I don’t know what to do anymore being stuck in the house isn’t helping
