The first thing to say is I regret it has taken so long for you to receive a reply, other that Sophie_M, who was on the ball. In this place your will be listened to and most will relate, May I ask waht MH condition you are struggling with?
Please let me emphasize the wait it is nothing to do with you personally, or the subject of your post, simply the system acting up
I doubt very much if it is any fault of yours that your relationships, and those of the people around you, run into difficulties. You are a caring soul and it sounds as if the needs of your freinds and their mental health problems have needed your support, a kind and giving act.
The only trouble is nobody is a bottomless well of strength, care and support - you are a human being, and that means you have limitations and have probably reached too far intro your own reserves, leaving you with less ability to cope than you need.
Not eating is no answer, we both know that , and will make matters worse. I know you have scoliosis and really hope that first it is not too bad, and secondly it is the type which lessens as one grows and matures. Healthy diet , good sleep and exercise would seem a good way to go, apart from anything else it tends to lessen anxiety of all sorts.
I realize the very idea of it may look upon yourself with disfavor, however I suspect this is you, and those around you may not feel the same, if in fact they even notice.
With your freinds can I suggest you approach them and say how you miss their friendship? Hopefully the basis of the argument can be settled quickly and then forgotten. Would you mind saying what it was all about?
Romantic relationships are another matter, for them to be more than a few dates and then forgotten there are basically a couple of common reasons to remaining together. Sex -obviously- is one, but an unequal one that does not always leave the giver with much self esteem.
The only way that really counts can include sex, but is based upon enjoying and having fun being with the other person, caring about them, trusting them and having those feelings returned.
It does not happen often. In a long life I've only ever found two I wanted to share my life with, and fortunately for me they have felt the same way.
I had girlfriends from school, but they never seemed to click, and were only partially interested, nothing lasted
Loving parents need to see the real condition of their children -how else can they help?
Are yours loving?
